摘要： A temperature measuring and identification (TMID) device obtains identification information and temperature information of a connected device having a temperature sensing circuit (TSC). The TSC includes a temperature sensing element (TSE) connected in parallel with a voltage clamping network (VCN) that limits the voltage across the TSE to an identification voltage within an identification voltage range when the voltage is greater than or equal to a lower voltage of the identification voltage range. When a voltage below the lower range is applied to the TSC, the VCN appears as an open circuit and the resistance of the TSC corresponds to temperature. A translation circuit within the TMID shifts TSC voltages within the identification voltage range to a normalization voltage range. Accordingly, voltages corresponding to temperature as well as voltages corresponding to identification are within the normalization voltage range. As a result, the resolution of a voltage sensing device used for measuring the temperature and identification voltages is maximized. In addition, the translation circuit maintains a minimal current during a rest state. For cost or other concerns, a first TSC may omit the VCN to provide a maximum identification voltage and other TSCs may include VCNs with lower identification voltage ranges.

摘要： A resettable short-circuit protection circuit can terminate excessive fault currents automatically and quickly. The short-circuit protection circuit is switchable and has a low input impedance during normal operation so that there is not a significant voltage drop across the switching elements of the protection circuit. The short-circuit protection circuit allows a power source internal to a portable device to be safely connected to an external accessory where there exists the possibility that the connection could be shorted at the time power is first supplied to the external accessory or a short develops afterwards. After terminating a short-circuit condition, the protection circuit may be reset by cycling an enable signal. The fault termination and reset timing may be configured by selection of internal resistance and capacitance values.

摘要： A communication protocol between a master device, such as a mobile phone, and a peripheral device facilitates authentication of the peripheral device. When a peripheral device is detected, the master device initiates a wake-up command to the peripheral device, transmits an authentication request command followed by challenge data to the peripheral device, and awaits responses from the peripheral device. The accessory receives the challenge data, performs a hash function on the challenge data, and generates response data. An authentication response type byte is sent to the handset followed by the response data. The handset compares the response data to pre-stored data that is associated with the challenge data. A match indicates that the accessory is authentic. The challenge/response data, also referred to as a plaintext/cyphertext pair, is pre-generated external to the handset using the hash function, then pre-stored in the handset.

摘要： Methods and apparatus for determining the operating states of a plurality of capacitive sensing buttons in a capacitive sensing user interface are disclosed. The capacitive sensing buttons are sampled in a round-robin fashion such that the decay time samples for the buttons are acquired in an interleaved manner during each sampling cycle. Provisions are made to reduce the initialization delay, to reduce transient-induced errors, and to obtain the operating states based on updated decay data samples for the buttons.
