Abstract: Systems and methods are provided related to a brace applied to a vehicle b-pillar. The brace may achieved reduced noise and vibration in the vehicle cabin. The brace may also achieve improved safety by preserving increased survival space for a passenger seated near the b-pillar in a side impact collision. The brace may include a base portion and two legs connected to the base portion at opposing sides. The based portion may include a first edge connected to a first side of the b-pillar and a second edge connected to a second side of the b-pillar. The legs may each connected a rocker at a distal portion. The shape of the brace may enable routing of force, energy, and/or load from the b-pillar to the rocker via the base portion and legs.

Abstract: Embodiments for a cerebrospinal fluid flow detector for detecting the flow of cerebrospinal fluid are disclosed. In some embodiments, the cerebrospinal fluid flow detector includes a casing with a rotatable wheel having a plurality of radially extending arms disposed therein. The rotatable wheel is in communication with a channel having a distal end in communication with an inlet port and a proximal end in communication with an outlet port such that the flow of cerebrospinal fluid through the channel causes the rotatable wheel to rotate. In some embodiments, each radially extending arm includes at least one radiopaque marker in which movement of the rotatable wheel caused by fluid flow through the channel allows an X-ray imaging apparatus to detect the difference in position of a respective radiopaque marker at multiple times caused by rotation of the rotatable wheel.

Abstract: The present invention relates to a system and method for calculating a quality index of a differentiated cell. To calculate the quality index, the present invention measures a differentiated cell by at least one metric, calculates a strictly standardized mean difference between the differentiated cell and a targeted cell, and calculates a mean squared error versus the target cell to define a value that represents the total difference between the differentiated cell and targeted cell based on the at least one measured metric.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for performing quadrature combining and adjusting. One example circuit may include first through fourth mixing circuits. The first mixing circuit may multiply a radio frequency signal with a first local oscillating signal to generate a first frequency converted signal. The second mixing circuit may multiply a radio frequency (RF) signal with a second local oscillating signal, which may be about 90° out of phase with the first local oscillating signal, to generate a second frequency converted signal. The third and fourth mixing circuits may multiply the RF signal with the second and first signals, respectively, to generate third and fourth frequency converted signals, respectively. A first combining circuit may combine the first and third frequency converted signals, and a second combining circuit may combine the second and fourth frequency converted signals.

The converter circuit comprises at least first and second inductors, each having an input and an output; a first input switch connected to the input of the first inductor; a second input switch connected to the input of the second inductor; and an output switch connected to the outputs of the inductors for selectively combining the outputs to form a parallel combination of the inductors or a series combination of the inductors. The controller generates signals for selectively connecting the first and second input switches and the output circuit between a pair of power supply input terminals and a pair of power supply output terminals. In response to appropriate signals from the controller, the converter circuit can be operated as a buck converter or a boost converter.

Abstract: A power control module receives a dynamic power control signal and generates a differential bias signal proportional to the dynamic power control signal. An analog multiplexer receives a digital amplitude signal including n bits and receives the differential bias signal. The analog multiplexer multiplexes the digital amplitude signal with the differential bias signal in parallel and generates a first differential signal. A driver module receives the first differential signal and a second differential signal. The driver module generates a first drive signal proportional to the dynamic power control signal when a bit in said digital amplitude signal is a logic one and the driver module generates a second drive signal proportional to the second differential signal when a bit in said digital amplitude signal is a logic zero.
