20090237155 | GENERATING A PHASE VALUE FOR A COMPLEX SIGNAL - A method of generating a phase value representative of a phase of a complex signal that includes an in-phase component and a quadrature-phase component includes determining a first sign for a first value and a second sign for a second value based on a quadrant occupied by the complex signal. The in-phase component is multiplied by the first value with the first sign, thereby generating a first multiplication result. The quadrature-phase component is multiplied by the second value with the second sign, thereby generating a second multiplication result. The first multiplication result, the second multiplication result, and a bias value are added, thereby generating the phase value for the complex signal. | 09-24-2009 |
20090310571 | Medium Access Control in Industrial and Automotive Wireless with Combined Wired and Wireless Sensor Networks - An embodiment of the invention relates to a local area sensor network including a central unit configured to receive a resource allocation request from a priority network sensor in a reserved timeslot and in response to designate a shared timeslot allocation. The priority network sensor transmits a resource allocation request in a reserved timeslot, and the sensor transmits data in the allocated shared timeslot. A sensor network can be formed with multiple gateways that each communicate over wired and wireless portions of the network. The central unit communicates with the gateways over the wired portion of the network. Wireless nodes communicate wirelessly with the gateways. The central unit receives a plurality of link quality indicators from the gateways for respective wireless paths to the wireless sensors, and selects a gateway for relaying a message from the central unit to a wireless sensor based on the link quality indicators. | 12-17-2009 |
20100233983 | SYSTEM INCLUDING RECEIVER FRONT ENDS - A system including an output node and receiver front ends. The receiver front ends are configured to receive an input signal. Each of the receiver front ends is configured to receive the input signal and provide an output signal at the output node. At least one of the receiver front ends is configured to selectively consume less power. | 09-16-2010 |
20120178401 | SYSTEM INCLUDING RECEIVER FRONT ENDS - An integrated circuit chip includes an output node, receiver front ends, and control logic. The receiver front ends are configured to receive an input signal. Each of the receiver front ends is configured to receive the input signal and provide an output signal at the output node. At least one of the receiver front ends is configured to selectively consume less power. The control logic is configured to select the number of receiver front ends providing an output signal to the output node based on a received signal strength indication. | 07-12-2012 |
20140139631 | DYNAMIC CONSERVATION OF IMAGING POWER - Representative implementations of devices and techniques provide adaptable settings for imaging devices and systems. Operating modes may be defined based on whether movement is detected within a predetermined area. One or more parameters of illumination or modulation may be dynamically adjusted based on the present operating mode. | 05-22-2014 |
20140145686 | CHARGE CONSERVATION IN PIXELS - Representative implementations of devices and techniques provide conservation of charge in a pixel. Charge in the pixel may be alternately stored in a first gate capacitance of the pixel and a second gate capacitance of the pixel. Transferring the charge between the gate capacitances conserves some or all of the charge, and reduces input power used to charge the gate capacitances. | 05-29-2014 |
20140312233 | TIME OF FLIGHT ILLUMINATION CIRCUIT - Some aspects of the present disclosure provide system and method of operation of a driving circuit for a light emitting element in a Time-of-Flight (ToF) camera. A DC-DC converter is configured to emit a constant current, and is coupled in parallel to a first modulation switch configured to connect the driving circuit to ground. The first modulation switch is further configured to alternate connections between the current source and ground at a frequency in a desired range of operation to produce an AC current. In some embodiments, an RC circuit element is coupled to an output electrode of the light emitting element and configured to apply a reverse bias to decrease turn-off time of the light emitting element. In some embodiments, a second modulation switch is coupled to the output electrode and configured to apply the reverse bias across the light emitting element. Other systems and methods are also disclosed. | 10-23-2014 |
