摘要： Methods and apparatuses are disclosed that allow an electronic device to autonomously adapt one or more user alerts of the electronic device. For example, some embodiments may include a method for operating a haptic device including driving a haptic device using a control signal, measuring a frequency related to the operation of the haptic device and comparing the measured frequency with a target frequency. A control signal is adjusted based on the comparison to drive the haptic device to the target frequency.

摘要： Universal Serial Bus (USB) repeater circuits and methods of operating the same for communicating data signals from a first pair of data terminals to a second pair of data terminals of the repeater. In a first channel, an amplifier stage in a receiver amplifies a differential signal received at the first pair of data terminals to generate a differential signal at first and second output nodes of the receiver, and a transmitting circuit transmits a differential signal at the second pair of data terminals responsive to the differential signal at the first and second output nodes of the receiver. The receiver includes a hysteresis stage that receives an offset in opposition to the differential signal at the first and second output nodes of the receiver. End-of-packet (EOP) dribble in USB communications in the HS mode is reduced by the offset at the hysteresis stage.

摘要： A control module for operation of downhole well tools and apparatuses is disclosed. The control module can control multiple tools, electronics, subs, etc. based on one electronic input and optionally one hydraulic input from the wellhead or surface. The control module can transmit along selected electronic lines and optionally hydraulic lines in order to control specific apparatuses of the downhole well tools. By allowing a single electronic line from the surface or shut in to control multiple tools, total electronic complexity is reduced. A three conductor control module can control operations of up to twelve downhole tools, and a two conductor control module can control operations of up to six downhole tools, in some embodiments.

The containing element comprises a stiff frame (10) defining a recess (20) to house the body part 200. The frame (10) comprises two lateral stiff guides (51) defining the recess (20) and the stiff support (30) is configured to move in a guided manner in the stiff guides (51). At least one servomotor (40, 40′) is provided connected integrally to the stiff frame (10) on the opposite side to the stiff support (30) with respect to the recess (20) and arranged to cause a relative movement, inside the recess (20) and with respect to the lateral stiff rails (51), of the stiff support (30) with respect to the body part (200). At least one belt (50, 50′) sliding parallel to the lateral stiff rails (51) and connected respectively with the servomotor (40) and the stiff support (30) is provided. The servomotor (40) is configured to operate the or each belt (50, 50′) to cause guided movement in the stiff guides (51) of the stiff support (30).

摘要： A sensor system includes an actuator, an accelerometer coupled with the actuator, a rigid member, a transducer, and one or more processors. The actuator generates motion. The accelerometer outputs an acceleration signal responsive to at least the motion of the actuator. The rigid member extends from a first end coupled with the accelerometer to a second end. The transducer is coupled with the second end of the rigid member. The transducer can be configured to couple with a load, and can output a force signal responsive to at least a portion of the motion of the actuator transmitted to the transducer via the rigid member. The one or more processors determine a mechanical impedance of the load based at least on the acceleration signal and the force signal.

摘要： Systems, apparatuses, and methods for saving power on a bus interface are described. A system includes a host, a device, and a repeater interposed between the host and the device. While the host and device are in a low-power state, the repeater monitors a first bus to determine if the device has woken up. When the repeater detects a remote wake-up event initiated by the device, the repeater generates an interrupt which is sent to the host. The host responds to the interrupt by initiating a resume wake-up event procedure that assumes the device is still asleep. In this way, the host is able to stay in the low-power state longer while also using a wake-up procedure that does not require the host to be aware of the existence of the repeater.
