  • Patent number: 10322268
    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.

  • Publication number: 20160203262
    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.

  • Patent number: 9088471
    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.

  • Patent number: 8917075
    Abstract: A direct current to direct current (DCDC) voltage converter is described comprising a controller and at least one converter circuit. 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.

  • Patent number: 8896276
    Abstract: A DC-DC converter, capable of operation in either a boost or buck mode, includes a voltage source connected to an input switch through an inductive element such that a closed loop is formed. The DC-DC converter includes a switching network that receives one or more clock signals from an external clock source. The switching network has a first terminal connected to the inductive element, a second terminal connected to a first capacitor, and a third terminal connected to a second capacitor, wherein the switching network enables charging of the first capacitor and the second capacitor based on one or more clock signals such that the first capacitor and the second capacitor are charged alternately. The DC-DC converter includes a filter connected to a fourth terminal of the switching network, wherein the first capacitor and the second capacitor discharge alternately based on the one or more clock signals through the filter.

  • Patent number: 8724355
    Abstract: A circuit exhibiting rectification and amplification characteristics. In particular, a full-wave rectifier, wherein the rectifier has the ability to simultaneously amplify and rectify an input voltage. The circuit comprises transconductor circuit, rectifying circuit and amplifying circuit. The transconductor circuit is adapted for receiving an input voltage from at least one voltage source. The input voltage is then converted into intermediate currents by the transconductor circuit. Thereafter, the rectifying circuit rectifies the intermediate currents current to produce a rectified current. Lastly, the amplification circuit amplifies the input voltage to produce the amplified voltage.

  • Publication number: 20110201105
    Abstract: The invention relates to cDNA libraries obtained from Tammar wallaby (Macropus eugenii) mammary gland tissue at different times (including day 23 pregnancy, day 130 lactation, and day 260 lactation). Lactation-associated polypeptides were identified from these cDNA libraries, and bovine homologues of the wallaby proteins are also disclosed. The proteins have a range of activities including anti-apoptotic activity, pro- or anti-inflammatory activity, cathelicidin anti-microbial activity, induction of trefoil proteins (and protection of epithelial surfaces), increased cell proliferation, and induction of cell differentiation (and loss of pluripotency).

  • Publication number: 20060255996
    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.
