International Classification:

US Classification:

326 95, 326121, 365203, 327544

Abstract:

A method and apparatus for shifting a dynamic circuit, driven by a one-shot clock, to a pre-charge mode, during a power-off mode, is provided. Under certain conditions, a floating node may be present in a dynamic circuit. One approach to prevent floating nodes involves the generation of a new one-shot clock signal that is supplied to the last dynamic circuit in the series of dynamic circuits before the output flop (“the final dynamic circuit”). The new one-shot clock signal is driven to a logical low value when the power-off signal has a logical high value. Another approach to prevent floating nodes involves modifying the final dynamic circuit to include a structure that, when the power-off signal has a logical high value, drives the dynamic node to either a logical high value or a logical low value to prevent the dynamic node from becoming a floating node.

US Classification:

713600, 713601

Abstract:

A technique for providing service processor (SP) access to registers, e. g. , control and status registers (CSRs), located within hardware modules of a computer system, ensures access to the CSRs within a predetermine time period. The computer system includes a host module (HM) and a plurality of client modules (CMs). The CMs each include one or more associated registers, and each of the CMs is separately addressable. At least one of the CMs operates at a different clock frequency than the remaining CMs and includes a clock synchronizer, which provides a clock signal to facilitate reading of or writing to the associated registers of the CM by the HM.

Abstract:

A circuit for deterministic unparking of a strand of a microprocessor having multiple clock domains is described. The circuit includes a first flip-flop and a second flip-flop. Each flip-flop has a data input connected to receive a respective unpark signal, a clock signal at respective clock frequencies, and a respective enable signal. Each enable signal is generated by a respective logic block, each including a counter and each operating at a respective one of the clock frequencies. The second flip-flop has a data input connected to an output of the first flip-flop, and outputs an unpark signal that is used to unpark a strand of the microprocessor in a deterministic manner.

International Classification:

H03K 190948

US Classification:

326 71

Abstract:

An input circuit to a semiconductor device may selectively accept different voltage logic levels (e. g. , TTL or CMOS) as selected by a preset selection signal. The selection signal activates an N-type or P-type transistor in the input circuit which alters the threshold switching voltage of the input circuit logic. By altering the input threshold voltage, both TTL and CMOS input signals may be correctly triggered. An additional circuitry may be provided to allow a low voltage circuit (e. g. , 3. 3 Volts) to be tolerant of higher voltage inputs (e. g. , 5 Volts). An isolation transistor isolates the input of the circuit from the high voltage signal, while a pulldown transistor pulls a high logic, high voltage signal down to supply voltage level.

Abstract:

Methods, apparatus, and systems to non-invasively determine intra-luminal placement and patency of a vascular access device. Patency and/or placement are estimated indirectly by measuring a physiological parameter which is indicative of proper patency and/or placement of the vascular access device in a patient. The measurement is compared to a reference value or calibration. If the comparison indicates indication of proper patency and/or placement, a signal is generated. The signal can be used in a number of ways. One example is to give a user-perceivable alarm or indication of proper patency and/or placement. Non-limiting examples include activating a light, an audible buzzer, a vibration, readable displayed text or graphics, or some combination of the same. The user can then have an indirect and at least semi-automatic way of estimating proper patency and/or placement of a vascular access device.

G06K 9/46

Abstract:

The present disclosure relates to systems, methods, and non-transitory computer readable media for identifying traffic control features based on telemetry patterns within digital image representations of vehicle telemetry information. The disclosed systems can generate a digital image representation based on collected telemetry information to represent the frequency of different speed-location combinations for transportation vehicles passing through a traffic area. The disclosed systems can also apply a convolutional neural network to analyze the digital image representation and generate a predicted classification of a type of traffic control feature that corresponds to the digital image representation of vehicle telemetry information. The disclosed systems further train the convolutional neural network to determine traffic control features based on training data.

Abstract:

Methods, apparatus, and systems to non-invasively determine intra-luminal placement and patency of a vascular access device. In one form, our device itself remains non-invasive, connecting at the vascular access device's hub outside the patient's body. Patency and/or placement are estimated indirectly by measuring a physiological parameter which is indicative of proper patency and/or placement of the vascular access device in a patient. The measurement is compared to a reference value or calibration. If the comparison indicates indication of proper patency and/or placement, a signal is generated. The signal can be used in a number of ways. One example is to give a user-perceivable alarm or indication of proper patency and/or placement. Non-limiting examples include activating a light, an audible buzzer, a vibration, readable displayed text or graphics, or some combination of the same. The user can then have an indirect and at least semi-automatic way of estimating proper patency and/or placement of a vascular access device. In one aspect of the invention, the technique is able to achieve this end by monitoring and detecting changes in the physiological parameter of systemic vascular pressure via pressure measurement in, at, or near the hub or other portion of a vascular access device that has a lumen placed intra-luminally, and then using the results of that monitoring to indirectly transduce conditions or states indicative of either good placement/patency or bad placement/patency of the vascular access device.

International Classification:

G06Q 10/08
G07C 9/00

Abstract:

A method for shipping and handling of goods based on automatically operated, dual-access storage boxes is provided with at least one computerized dual-access storage box, at least one vehicle-authentication module, a central server module, and at least one courier vehicle. the vehicle-authentication module performs an authentication process on the courier vehicle goes for conditional access to the computerized dual-access storage box. The central server module receives an authentication request from the vehicle-authentication module. Accordingly, the vehicle-authentication module performs a first unlock event, if the courier vehicle is granted an authentication confirmation. This automatically opens a vehicle-side door for delivery of a cargo. Similarly, the central server module receives a user unlocking request. Accordingly, the central server module performs a second unlock event if the user unlocking request is verified. Further, the central server module executes the second unlock command wherein a recipient-side door is automatically opened.
