Abstract: An imaging device includes a controller and a generator. The controller controls an imaging unit on the basis of a command and data received from a host in accordance with an I2C/I3C communication protocol. The generator generates a second control signal indicating whether or not to apply intra-frame dynamic frequency scaling (DFS) or intra-frame dynamic voltage frequency scaling (DVFS) on the basis of a first control signal received from the host via a first route different from the I2C/I3C communication protocol, and outputs the second control signal to the host via a second route different from the I2C/I3C communication protocol.

Abstract: An infrared (IR) signature matching system comprises a heating and cooling device, a plurality of sensors configured to detect information related to the IR signature of the heating and cooling device and a background environment, a controller operably coupled with the heating and cooling device and the plurality of sensors. The controller is configured to receive the information from the plurality of sensors and adjust the temperature of the heating and cooling device until the IR signature of the heating and cooling device and the IR signature of the background environment are at least substantially matched in a selectable sub-region of the IR spectrum. Other systems, control circuits and related methods for matching IR signatures and cloaking objects in the IR spectrum are disclosed herein.

Abstract: A bulb changing system for elevated light bulbs is presented. The system has an elongate tube, a drive shaft with a drive handle, a drive gear, a driven gear, and a light receptacle configured to engage an exterior portion of the light bulb. In one aspect, the drive housing houses the drive gear and the driven gear therein a drive cavity and rotation of the drive handle causes the drive gear to rotate substantially along the longitudinal axis of the elongate tube, which in turn, causes the driven gear to rotate, which in turn, causes the light receptacle to rotate. As such, the light bulb is rotated into or out of engagement with a socket, depending upon the direction of rotation.

Abstract: A spool valve 10 for a variable camshaft timing (VCT) phaser for an internal combustion engine comprises a spool 11 slidable in a bore 12 in a valve sleeve 13, the spool 11 having spaced apart lands 14-17 dividing the bore 12 into chambers 41, 42, 43 between adjacent lands. The valve sleeve 13 has fluid passages 22-27 including a lock passage 26 communicating with a lock pin 31, a vent passage 27 communicating with a fluid sump 35, and a lock pin oil feed passage 22, with the spool 11 being slidable in the bore 12 to interconnect select passages via particular chambers, wherein the vent passage 27 and the lock pin passage 26 are connectable with different chambers 43 and 42 respectively. The arrangement avoids unnecessary operation of the lock pin 31.

Abstract: The present invention provides a connector arrangement operative to connect a prime mover driven alternator to an alternating current circuit with an existing alternating current. For example, the connector arrangement may be used to connect an alternator driven by a Stirling engine to an alternating current mains electricity supply. The connector arrangement includes a circuit with an adjustable resonant frequency, adjustable between a first resonant frequency tuned to an initial operating frequency of the prime mover and a second resonant frequency detuned to the initial operating frequency. This adjustable resonant frequency is beneficial as it allows operation to be tailored to the exact operating conditions of the prime mover that is likely to have its own resonant frequency that may vary according to its operating condition.
