Abstract: A radar apparatus includes a receiver having a plurality of receiver channels, each including an antenna element, a phase shifter, and a switch. The antenna element provides a signal that passes through a phase shifter to a switch. The signal may then be passed to a summing element if the switch is closed. The summing element receives signals from the receive channels, and provides a sum signal to a mixer. In phased array mode, the switches are closed and antenna controller adjusts the phase angles of the phase shifters. In DBF mode, the phase shifters are maintained at a set value, and switches are operated sequentially to provide time-multiplexed signals from the receive channels to the summing element.

Abstract: A valve for a magnetorheological fluid is formed with a duct through which the magnetorheological fluid can flow and which can be exposed to a variable magnetic field such that the flow resistance of the duct can be set using the magnetic field in the duct. The magnetic field can be lastingly generated using a magnet device that is made at least in part of magnetically hard material. The magnetization of the magnet device can be lastingly modified by a magnetic pulse of a magnetic field generation device in order to lastingly change the magnetic field in the duct and thus the flow resistance of the duct. A valve of the invention requires energy only to change settings while a specific setting can be lastingly maintained without supplying energy.

Abstract: The present disclosure provides systems and methods for protecting a switch mode power supply (SMPS). An SMPS may include an input power connector, an input rectifier and filter, a transformer, an output rectifier and filter, and an output power connector. A control circuit may selectively generate a switching signal for driving the transformer based on a feedback signal and a protection signal generated by a protection circuit. The protection circuit may generate the protection signal with an asymmetric duty cycle oscillating between an enable state and an inhibit state. The protection signal may inhibit the control circuit from generating the switching signal when the protection signal is in the inhibit state. A detection circuit may receive the feedback signal and selectively force the protection signal to the enable state when the feedback signal indicates that an output voltage is too high.

Abstract: An internal bidirectional tubing plug for plugging a well to prevent well fluids from passing the plug in a well conduit until the internal components of the plug are pumped out of its body. The body of the plug connects to the well's tubing string. The body holds a petal assembly consisting of several petals and a tapered cork assembly located within an opening formed by the petals. Both assemblies are sandwiched between upper and lower pistons. Hydrostatic pressure on the bottom of the plug as it is lowered into the fluid filled well holds the petals within the body. The internal components of the plug are removed from the body by applying hydraulic pressure in the upper area of the plug. This causes the plug to fail at a recess provided in the cork, resulting in the two assemblies and the pistons being forced out of the body.
