Abstract: In one embodiment, an ultrasonic flow meter is provided for measuring a flow rate of a medium flowing through a conduit, the ultrasonic flow meter comprising two ultrasonic emitters and two ultrasonic receivers mounted to the conduit. The flow rate is determined based on a first time interval of a first ultrasonic signal traveling from the first ultrasonic emitter to the first ultrasonic receiver, and a second time interval of a second ultrasonic signal traveling from the second ultrasonic emitter to the second ultrasonic receiver. In some embodiments, the first and second ultrasonic signals travel in a downstream direction with respect to the flow. In other embodiments, the first ultrasonic signal travels along a first transmission path that forms a first angle between the first transmission path and the flow direction, while the second ultrasonic signal travels along a second transmission path that forms a second and different angle between the second transmission path and the flow direction.

Abstract: A control assembly controls removal of a circuit board from a chassis. The control assembly includes a support member configured to fasten to the circuit board, and a handle pivotally attached to the support member. The handle is configured to swing from an opened position to a closed position relative to the support member during installation of the circuit board within the chassis, and from the closed position to the opened position during removal of the circuit board from the chassis. The control assembly further includes a button configured to move between a biased position and a depressed position relative to the support member. The button is further configured to (i) inhibit removal of the circuit board from the chassis when the button is in the biased position, and (ii) enable removal of the circuit board from the chassis when the button is in the depressed position.

Abstract: Techniques are provided for increasing flexibility to I/O banks with respect to supply voltages. Multiple supply voltages can be provided to a bank of I/O pins. Separate I/O pins residing in an I/O bank are driven by buffers that are coupled to different supply voltages. Dedicated I/O pins are driven by buffers with pre-selected supply voltages. The dedicated I/O pins can be grouped together into the same I/O bank providing greater flexibility to drive signals on I/O pins in other I/O banks at different voltages. Also, a dual mode input buffer can drive an input signal to a voltage determined by one of two possible supply voltage levels. In addition, power on reset circuits for an I/O bank can monitor the voltage of two or more supply voltages.

Abstract: Deserializer circuitry for high-speed serial data receiver circuitry on a programmable logic device (“PLD”) or the like includes circuitry for converting serial data to parallel data having any of several data widths. The circuitry can also operate at any frequency in a wide range of frequencies. The circuitry is configurable/re-configurable in various respects, at least some of which configuration/re-configuration can be dynamically controlled (i.e., during user-mode operation of the PLD).
