Abstract: A device and method of controlling a device. The device may include a controller for controlling operation of a pumping device to producing a flow of fluid in the pump set, the controller including a processor and a memory, the controller being adapted to store in the memory, syringe size data, the controller configured to execute in the processor a syringe detection program to determine a presence and size of the syringe loaded onto a flow control apparatus.

Abstract: A light fixture delivering electrically controlled lighting distributions for mounting within an installed panel system typically used in ceiling and wall constructions and incorporating acoustic, drywall or wood panels. The light fixture can provide low-glare or wide spread “batwing” ambient light or more directional wall wash, task and accent lighting. The light fixture comprises one or more LED boards and an optical element which can be back-lit or edge-lit. The light fixture body is configurable, comprising a 3-dimensional extruded elongate body with its ends cut at a configured angle. The body typically comprises additional side support features that support and enclose the edge of installed panels. In the case of a T-bar based ceiling grid system the side support features may also replicate the function and appearance of T-bar horizontal and vertical portions. The body comprises features to retain and align LED boards, reflectors and a back-lit or edge-lit optical element.

Abstract: A lighting assembly includes at least one light source array provided in a housing and a light scattering primary transmissive optical element having at least one focal region positioned substantially parallel or concentric with the light source array. Lens features of the optical element may include a Fresnel lens pattern to produce at least one focal region. An auxiliary transmissive optical element may be provided to further control light distribution and brightness uniformity.

Abstract: A transceiver for fiber optic communications. The transceiver can include a transmitter module having a transmitter host interface configured to receive an input host signal; a transmitter framer configured to frame the input host signal and to generate a framed host signal; and a transmitter coder configured to encode the framed host signal to generate an encoded host signal for transmission over a communication channel. The transceiver can also include a receiver module having a bulk chromatic dispersion, fiber length estimation, and coarse carrier recovery circuit configured to equalize a digital input ingress signal to generate an equalized ingress signal; a receiver framer configured to frame the equalized ingress signal to generate a framed ingress signal; and a receiver host interface configured to output the framed ingress signal. The receiver host interface is compatible with a framing protocol of the receiver framer.

Abstract: A calibration process determines a desired supply voltage for operating an electronic device. During the calibration process automatic test equipment controls a power supply to sweep the supply voltage to the electronic device across a predefined voltage range while monitoring a performance characteristic of the electronic device. The automatic test equipment determines the desired operating voltage based on a minimum supply voltage at which the monitored performance characteristic meets a minimum acceptable performance standard and stores the desired operating voltage to a non-volatile storage. During a startup sequence, the electronic device controls the power supply to provide the desired operating voltage as the supply voltage to the electronic device.
