Filed: 2019-11-25
Abstract: A controller provides power to (i) a first light-emitting device that emits a first white light of a first correlated color temperature (CCT) and (ii) a second light-emitting device that emits a second white light of a second CCT. The second CCT is lower than the first CCT. The first and second white lights mix to yield a combined white light having a combined CCT with a combined brightness. The controller receives a user-adjustable DC input voltage Vin.  The controller distributes supply power to the first and second light-emitting devices according to a power-distribution scheme that differentiates between whether Vin is in an upper range or a lower range, as follows: (i) In the upper range: as Vin decreases, combined-light CCT decreases and combined-light brightness remains constant. (ii) In the lower range: as the Vin decreases, combined-light brightness decreases.

Abstract: A method is performed by a wireless communications device of transmitting measurement reports to an infrastructure equipment. The method comprises receiving signals transmitted by the infrastructure equipment, measuring a characteristic associated with the received signals, and selecting an index value from one of a plurality of index values. Each of the index values represents a range of values of the characteristic for which communications parameters of a transmitter in the infrastructure equipment and a receiver in the communication device should have to achieve an acceptable communications performance for values of the characteristic within the range of values of the characteristic. The selected index value represents the communications parameters of the transmitter and the receiver which will satisfy the acceptable communications performance over a range of values of the characteristic including the measured value of the characteristic. The method further comprises, subject to the selected index value, transmitting the selected index value to the infrastructure equipment. Furthermore, a separation between the range of values of the characteristic for communications parameters achieving an acceptable performance corresponding to at least two of the plurality of indexes is not equal to a separation between the range of values of the characteristic for communications parameters achieving an acceptable performance corresponding to two others of the plurality of indexes.

Abstract: An ultrasound imaging system includes a processor that is programmed to operate the system in a normal operating state and two or more lesser power states. The processor lowers the operating power state to a lesser power state upon detecting one or more operating conditions such as no tissue been imaged in a predetermined time limit or that the imaging system or transducer has not been moved in a time limit. Upon awakening from a power off state, the processor implements a lesser power state before operating at the normal operating state to avoid undue power use until the transducer is positioned to image tissue.
