Abstract: A voltage/current regulator supplying controlled current with PVT headroom adjustment. In an example application, an LED backlight driver controls ILED string current, and controls a voltage regulator supplying VOUT string voltage with sufficient headroom voltage VHDRM to supply the ILED string current. The LED driver controls ILED string current with an MLED current control transistor, including gate drive referenced to a reference voltage VREF. VOUT/VHDRM are adjusted for PVT operating conditions by generating a replica/reference current ILED/RATIO (proportional to ILED string current) with a replica current control transistor MLED/RATIO based on VREF. ILED/RATIO is mirrored to a second replica MLED/RATIO transistor that saturates at a PVT_REF reference voltage corresponding to a minimum voltage that can supply the required ILED current (as represented by the ILED/RATIO replica/reference current), accounting for PVT operating conditions.
Abstract: The disclosure provides a detector that includes a pre-charge circuit. The pre-charge circuit receives a supply voltage. A pre-charged comparator is coupled to the pre-charge circuit and receives the supply voltage. The pre-charged comparator generates a transition signal at a transition node. A slope of the transition signal is greater than a slope of the supply voltage. A first diode connected transistor receives the supply voltage. A first capacitor is coupled to the first diode connected transistor. An inverter is coupled to the first diode connected transistor and generates an enable signal when the supply voltage is below a threshold voltage.

Abstract: A frac plug system for use at the end of well drill string in a fractured underground formation, including an elongated mandrel body, a nose cone, a mandrel head, and a sealing assembly; at least one sensor positioned on the nose cone, the sensor being optionally a temperature sensor, pressure sensor, pH sensor, or fluid composition sensor; a battery operated microcontroller located in the mandrel body, the microcontroller constructed and arranged to periodically read the data output of the sensor and store the data from the sensor; a transmitter constructed and arranged to transmit the stored data from the set of sensors to a receiver on a pup joint when the receiver is in receiving range of said transmitter, the receiver constructed and arranged to write the transmitted stored data to an electronic memory; and whereby the data may be retrieved from the electronic memory.
Abstract: According to certain embodiments, a method in a network node is disclosed. The method comprises selecting a subset from a predetermined set of P CSI-RS ports for receiving channel information. The network node comprises an antenna array with controllable polarization. Each CSI-RS port corresponds to a combination of a set of resource elements and an antenna port of said antenna array. The predetermined set comprises a first number P[subscript]1 [/subscript]of CSI-RS ports with a first polarization state and a second number P[subscript]2 [/subscript]of CSI-RS ports with a second polarization state. The first and second polarization states are distinct. The method further comprises populating the subset with Q CSI-RS ports in such manner that the ratio of CSI-RS ports respectively having the first and second polarization states is equal to the ratio of the first and second numbers.

Nvidia is typically conservative with its reported boost clocks, with most cards running well above the given speed. The 'stock' GTX 1650 has a boost clock of 1665MHz, giving it 2984 GFLOPS of theoretical performance. That's less than the GTX 1060 cards, but roughly 50 percent faster than the GTX 1050. The GTX 1650 is also designed to run without a 6-pin PCIe power connector, though factory overclocked cards (like the MSI GTX 1650 Gaming X 4G that I'm using) have higher clockspeeds and require a 6-pin PEG connector.
Abstract: A surgical probe includes a cannula assembly, having a graded index (GRIN) fiber that is configured to receive a multi-spot light beam at a proximal end and to emit the multi-spot light beam at a distal end; an adapter, having a distal end, configured to receive the cannula assembly, with the proximal end of the GRIN fiber, a proximal end, configured to couple to a light guide via a connector and to receive a light delivered by the light guide from a laser source to the adapter, and an interface, configured to couple the light delivered by the light guide to the proximal end of the GRIN fiber; wherein a length of the GRIN fiber is sufficiently long that the interface is outside a patient”s eye during a photocoagulation procedure.
“I found a glass swizzle stick, that was cool,” she said. “The coolest was a poison bottle I found about a year ago. I took it home and was rinsing it off, and I got a closer look. It’s a tiny brown bottle with a skull and crossbones. Oh, and an amethyst I found in OB … It’s always exciting to find the clay pipes from the 1700s.”
A unanimous show of industry support has welcomed the federal government’s announcement of $2.2 billion funding aimed at road safety enhancements and heavy vehicle initiatives.
The SIT meeting every month would decide the policy to minimise and avert road accidents. The SITs will be headed by respective deputy superintendents (Hqr) of the police districts, having assistant engineer R&B, motor vehicle inspectors and an official from traffic police as its members.
Paws and Read: May 1 at 6:30 p.m. School-age children are invited to come practice reading with Therapy Dogs International volunteer teams. The main objective of this program is to provide a relaxed and “dog-friendly” atmosphere, which allows students to practice the skill of reading. Some children have difficulties reading and, as a result, have developed self-esteem issues. By sitting down next to a dog and reading to the dog, all threats of being judged are put aside. The child relaxes, pats the attentive dog and focuses on the reading. At Paws and Read, children practice the skill of reading, build self-esteem and associate reading with something pleasant. Space is limited, and registration is required.
