Abstract: A tricuspid valve apparatus may include a frame and an associated neo-prosthetic valve. The frame acts as a stabilizing structure that extends cephalad into the morphologic or functional right atrium (upstream) and caudally into the morphologic or functional right ventricle (downstream). The frame comprises a strutted atrial dome that conforms to the atrium without obstruction of blood flow from the incoming great veins (i.e. superior vena cava and inferior vena cava) or other anomalous veins and/or tributaries. The frame further comprises ventricular struts to be placed within the right ventricle to secure the neo-prosthetic valve in a desired position. The assembly of the frame and valve is collapsible so that prior to deployment the assembly is placed in a vascular catheter, and then self-expands upon release in the heart.

Abstract: An Automated Teller Machine (ATM) terminal receives a transaction request from a user. The ATM terminal triggers a camera to capture a first image of the authentication media item presented by the user, where the first image of the authentication media item is embedded with a first unique code. The ATM terminal compares the first image of the authentication media item with a second image of the authentication media item that is associated with the user, where the second image of the authentication media item is embedded with a second unique code for verifying the user. The ATM terminal determines whether the first unique code corresponds to the second unique code. The ATM terminal conducts the transaction request if it is determined that the first unique code corresponds to the second unique code.

Abstract: Noise reducing circuitry may be included in a pulse width modulation circuit. The pulse width modulation circuit may include a comparator adapted to receive an analog signal and a sawtooth signal and to compare such signals to generate a pulse width output. In general, the noise reducing circuitry may include a sawtooth signal generating circuit configured to generate a sawtooth signal including an up ramp and a sawtooth signal including a down ramp. A control circuit may be coupled to the sawtooth signal generating circuit for controlling the sawtooth signal generating circuit based on whether a relatively narrow or relatively wide pulse width is to be output by the pulse width modulation circuit. Methods for reducing noise in a pulse width modulation circuit may generally involve dynamically controlling a direction of ramp of a sawtooth signal that is to be input to the comparator of the pulse width modulation circuit.

Abstract: A pin-limited device includes a pattern-recognition circuit that detects a predetermined signal pattern transmitted on a supply pin of the device. The predetermined signal pattern is generated within the acceptable operating voltage range of the IC device (e.g., between the minimum and maximum acceptable system voltage levels utilized to control the internal circuitry of the device). Accordingly, the pin-limited IC device continues to operate within specifications while the predetermined signal pattern is transmitted on the selected power supply pin or pins. A test mode circuit generates a switch control signal in response to the predetermined signal pattern to connect an output pin of the device, for example, to an internal node of the device. The pattern recognition circuit sets a latch when the predetermined signal pattern is detected, and the latch is reset when the device is powered down then powered up.

Abstract: A circuit, method, and system for intelligently soft starting switching regulators are provided. The circuit, method, and system provide for a switching circuit operable to couple an input voltage to an output of the switching regulator in response to a control signal, a controller operable to generate the control signal to control the switching of the switching circuit based in part on a reference voltage, and a soft start circuit operable to provide the reference voltage to the controller responsive to the switching of the switching circuit.

Abstract: Apparatus and methods for rapidly diagnosing the presence or absence of the symptoms of neurological pathology caused by physical head trauma (such as occurs in contact sports or automobile collisions), disease (such as occurs in Alzheimer's disease), toxins (substance abuse or environmental toxins) or infection (such as occurs as a side effect of later-stage AIDS infection). These inventions are useful for diagnosing neurological pathology, as well as for monitoring recovery from or maintenance or progression of neurological pathology.

Abstract: A filtering apparatus comprising an elongate container body, an inlet, an inlet reservoir, an outlet, an outlet reservoir, and at least two filter elements, wherein each filter units contains two or more space-apart and co-axially stacked filter elements encased in a cylindrical-shaped filter cartridge. Contaminated fluid flows from the inlet, through the perforations located on the inlet reservoir separator, and into the elongate container body. Fluid flows into the filter units through perforations in the filter cartridge and the open ends of the filter cartridge. The filter units use an opposed axial flow method to draw the fluid through the filter elements. The filtered fluid flows through a perforation in the axial conduit, passes through the axial conduit outlet into the outlet reservoir. The filtered fluid then exits through the outlet. The present invention may be used in operation with a motor and pump to filter large flow rates and volumes of contaminated fluid.
