摘要： A fluorescent lamp starter unit determines whether the lighting fixture into which it has been plugged is in a first state (for example, the lamp is off) or is in a second state (for example, the lamp is on). If the fixture is in the first state then the starter unit uses a first method to detect ballast type, whereas if the fixture is in the second state then the starter unit uses a second method to detect ballast type. In one example, the first method involves turning on the power switch of the starter unit at a time after a zero-crossing and then using the periodicity of a transient switch current signal to determine ballast type, whereas the second method involves turning on the power switch at the time of the zero-crossing and then using peak amplitude information of the transient switch current to determine ballast type.

摘要： A microcontroller has an integrating analog-to-digital converter (IADC) with an in-situ autocalibrating functionality. On-chip autocalibrating circuitry supplies a first predetermined analog input voltage to the IADC and obtains a first data value from the IADC. The autocalibrating circuitry supplies a second predetermined analog input voltage to the IADC and obtains a second data value. The first and second data values are used to calibrate the IADC such that if the first input voltage is later supplied to the IADC, then the IADC will output a first predetermined desired digital output value and such that if the second input voltage is later supplied to the IADC, then the IADC will output a second predetermined desired digital output value. The first and second analog input voltages are generated on-chip so the calibration is performed automatically without having to supply external calibrating signals to the microcontroller. Other related methods and circuitry is disclosed.

摘要： A microcontroller receives a supply voltage (VCC) from one or more batteries. Rather than automatically resetting the microcontroller if VCC drops below a VBO voltage, a latent VBO reset circuit does not reset the processor if VCC drops below a second voltage (VBO) as long as VCC does not fall so low that a power on reset (POR) circuit of the latent VBO reset circuit is tripped. The processor continues to operate as long as it can below VBO, thereby maximizing battery usage. When VCC rises to a third voltage (for example, due to battery replacement), then the latent VBO reset circuit automatically resets the processor to remove potential ill-effects of having operated below VBO. User data stored in volatile memory is not lost during battery replacement. A special VBO bit in a processor-readable status register indicates that the microcontroller operated below VBO.

摘要： An Improved Circuit Design and Optics System for infrared Signal Transceivers is disclosed. The preferred system includes an IR transceiver assembly that is easily grasped by assemblers. Furthermore, the primary and secondary lenses associated with the transceiver system are easier to manufacture than are current lens designs. Also, the heretofore critical lens separation between the infrared emitting and infrared detection devices and the primary lens is rendered a flexible dimension, dependent only upon the particular appliance in which the system is installed. The present invention permits the stand for infrared emitting and infrared detection devices to be eliminated as a result of exchanging a non-imaging transceiver system with the current imaging transceiver system. The present invention further comprises assembling or otherwise combining infrared emitting and infrared detection devices into a single infrared emitting/infrared detection device stack. Finally, the present invention provides an infrared transceiver assembly that has a smaller footprint by backside mounting and/or stacking the discrete devices.

摘要： A memory device includes memory cells that are overwritten in response to receipt of a clear request signal and an overwrite value. The clear request signal enables all word lines of the memory device to be overwritten. The clear request signal in combination with the overwrite value cause the overwrite value to be written to a first column of memory cells. At least two delay elements transfer the overwrite value to another column of memory cells after a delay. By use of at least two delay elements to delay and transfer the overwrite value to be written to another column of memory cells, a relatively low magnitude of current can be used to cause memory cells to be overwritten. In addition, the value and sequence of values that overwrite memory cells can be controlled.

摘要： A system efficiently expands program memory without extensively modifying the remaining microcontroller architecture. An address bus of N+M bits addresses 2N memory locations in a regular portion of program memory and additional memory locations in an expanded portion. An N-bit program counter increments through instructions stored only in the regular portion. Constants are stored in both the regular and expanded portions. An M-bit page-designator is prepended to an N-bit operand to generate a memory address of N+M bits. Program memory is expanded only when a load instruction retrieves constants from program memory. The page-designator is toggled when an N-bit operand rolls over upon incrementing by the load instruction. A block of constants straddling the boundary between the regular and expanded portions can be retrieved from program memory by executing only the load instruction. When program instructions are executed that do not retrieve constants, a fixed page-designator designates the regular portion.

摘要： A portable electronic device with an IrDA transmitter LED is used to transmit both IrDA signals and remote control infrared signals. The device transmits remote control infrared signals with reduced power consumption. During a relatively longer remote control signal pulse, an inductor saturates and stores energy when a drive current flows from a power supply, through the inductor and then through the LED. An energy-transferring circuit transfers a portion of the energy stored in the inductor to the power supply. Energy is transferred when the drive current is cut and the voltage across the inductor surges, which causes an overflow current to flow through a diode in the energy-transferring circuit and to the power supply. The inductor is a planar coil of traces on a printed circuit board and therefore costs less to manufacture than does a toroidal coil of wires.

摘要： A keypad encoding circuit contains a voltage dividing network and an integrated circuit. The voltage dividing network includes a string of resistors that generates an encoding signal voltage. The integrated circuit converts the encoding signal voltage into a digital value indicative of which of the keys has been pressed. The cost of the voltage dividing network is reduced by forming the resistors from a layer of conductive carbon and avoiding the cost of providing discrete resistors. Each resistor has the same resistance even where the dimensions of the conductive carbon patches that form the resistors vary. Providing the resistors does not involve additional manufacturing cost because the resistors are made in the same step as are the landing pads of the voltage dividing circuit. Manufacturing costs associated with etched printed circuit board layers are avoided because inexpensive printed layers are used to realize the required traces and resistors.

摘要： In an auto baud system and method, the baud rates between two communicating devices are synchronized by timing the transmission of a plurality of bits by counting the cycles of a reference clock. The number of cycles counted is then divided by the number of bits counted over and any remaining cycles are distributed evenly across the data being transmitted or received. The interface of the circuit is preferably implemented as a single pin, open drain interface which can be connected to an RS-232 communications link using external hardware.

摘要： A bandgap reference circuit (BGRC) that is suitable for low-supply voltage applications outputs an adjustable reference voltage. In an operational mode, main currents flow through diodes and are controlled by a main current generator such that a positive temperature coefficient of a voltage across a resistor compensates for a negative temperature coefficient of a voltage across the diodes. The difference of the voltages across the diodes increases with temperature and is used to generate the main currents having positive temperature coefficients. The BGRC ensures sufficient current flow through the diodes during startup. In a startup mode, a startup current generator outputs startup currents that combine with the main currents and prevent the BGRC from operating at incorrect operating points that would otherwise be stable when insufficient current flows through the diodes. The startup currents are generated when the voltage drop across the resistor is less than a predetermined voltage offset.
