A surgical spring clip includes a first molded component having a first jaw and a first finger tab. A second component having a second jaw and a second finger tab comprises the only other molded component. The first component has a telescoping relationship with the second component and is moveable by operation of the finger tab between a first position wherein the jaws are generally closed and a second position wherein the jaws are generally open. A spring disposed between the tabs and the jaws biases the first and second components toward the first position. The clip has a telescoping barrel with the general shape of a polygon in radial cross-section. An increased guidance link provides the clip with a guidance ratio of about 1.5 ratio. Alignment of the components is further enhanced by the provision of ramped projections and the accommodation of tolerances only along one side of the telescoping barrel. A simplified method of assembly requires movement of the second component through a window in the first component.

The invention relates generally to the field of wireless communications and more particularly to a method of and device for detecting the presence of a received data packet in a digital receiver. The present invention proposes a simplified method of correlation by removing dependency on the amplitude fluctuations while at the same time maintaining phase relevancy. The key advancement involves mapping the complex quadrature amplitude modulation (QAM) preamble to a quantized phase shift keying (PSK) constellation before application to a matched complex correlator. The proposed process essentially “amplitude normalizes” the input signal without the use or complexity associated with a divider. This simplified normalization scheme makes the packet detection algorithm robust against amplitude variations in the input signal, while still allowing for good correlation output. In applications where interference is superimposed on the I/Q input signals, the invention improves the detection capability over automatic gain control (AGC) normalization methods.

The present invention provides a simplified method of controlling power among the various sources and loads in a power system. Power generating sources are each connected to a common DC bus through a converter designed to optimize power flow to the DC bus. A DC storage device is connected to the common DC bus through a power regulator designed to maintain a constant voltage on the DC bus. Further, an inverter may be provided to convert the DC voltage to an AC voltage for a customer load or for connection to the utility grid. Each power conversion device is independently controlled to provide a modular and simplified power control system.

A method for calculating a flip angle schedule for a train of refocusing radio frequency (RF) pulses with reduced flip angles allows control of RF power deposition and use of a longer echo train. A target signal is defined for each echo in the echo train, and flip angles are then calculated from the target signals. The target signal schedule includes two phases. In the first phase, the target signals drop asymptotically to efficiently establish a pseudo-steady state at a pre-defined minimum signal level, S_min. In the second phase, the target signal is increased monotonically for the remainder of the train to a pre-defined maximum signal level, S_max. By increasing the target signal, the effect of relaxation may be reduced, decreasing blurring and ringing artifacts. Flip angles are then calculated from the target signal schedule, using a simplified method that requires no information about the tissues' relaxation properties.

An apparatus, method and computer program product provide a simplified method for unlocking an electronic device that uses soft keys, such as capacitive touch keys, or proximity detection areas and patterns. The keys may be implemented in the form of areas of a sensor, and a processing circuit observes a touch pattern (or proximity pattern, or characteristic pattern such as a capacitance pattern of a user's finger) and compares the same with the registered pattern to determine if there is a likeness. In doing so, the electronic device is operated at a low power state, and in that low power state observes whether a predetermined pattern is observed and when it is, unlocks the electronic device for interaction with a user at a fully operational state.
