摘要:
An improved accessory light for breast pumps apparatus is described. This improved accessory light for breast pumps apparatus may be secured or affixed to various models of breast pumps to allow the user to have a hands-free, illuminated view of the milk being expressed from the breast. The accessory light may consist of a clamp-based accessory secured to a breast shield neck or an accessory that is secured to the breast shield back using a flexible material.

This invention provides methods of detecting and quantifying target nucleic acids in samples in multiplexed single chamber reactions. Consumables incorporating chambers optimized to reduce signal background proximal to high efficiency arrays are provided, as well as methods of use. Devices and systems configured to use the consumables to practice the methods are a feature of the invention.
摘要:
A junction field effect transistor having a drain and a source, each defined by regions of a first type of semiconductor interconnected by a channel, and in which a dopant profile at a side of the drain facing the channel is modified so as to provide a region of reduced doping compared to a body region of the drain. The region of reduced doping and the body region can be defined by the same mask and doping step, but the mask is shaped to provide a lesser amount and thus less depth of doping for the region of reduced doping.
摘要:
A bipolar transistor, comprising a collector, a base and an emitter, in which the collector comprises a relatively heavily doped region, and a relatively lightly doped region adjacent the base, and in which the relatively heavily doped region is substantially omitted from an intrinsic region of the transistor.
摘要:
A bipolar transistor comprising an emitter region, a base region and a collector region, and a guard region spaced from and surrounding the base. The guard region can be formed in the same steps that form the base, and can serve to spread out the depletion layer in operation.
摘要:
Predistorting an input signal prior to amplification in an RF power amplifier (206) includes isolating a plurality sub-band signals, each representing a portion of the input signal s(t). The method includes independently modifying an amplitude and a phase of each of the plurality of sub-band signals. The modification of the amplitude and/or phase is performed using a set of signal weighting parameters (weights) w and W, controlling linear and nonlinear modifications respectively, which are determined in an adaptive process by an adaptive controller (224). After modification, each of the sub-bands are summed together to obtain a predistorted input signal for an RF power amplifier (206).

A method for operating a communications system is provided. The method includes receiving a plurality of signals at a plurality of antenna elements, the plurality of signals arriving at the array of antenna elements at a plurality of angles of arrival (AOAs) with respect to a reference location. The method also includes calculating a plurality of differential distance vectors between the plurality of antenna elements and the reference location, each of the plurality of differential distance vectors associated with one of the plurality of AOAs and at least one of the pluralities of signals. The method further includes obtaining a plurality of actual phase center locations for the plurality of antenna elements based on the plurality of differential distance vectors and the plurality of AOAs and providing a correction to configuration data for the array of antenna elements based at least on the plurality of actual phase center locations.
