Abstract: An apparatus for multiphase clock calibration for a transmitter in data communication systems includes a phase interpolator (PI) configured to receive a clock signal and generate multiphase clock signals with adjustable duty cycles and in-phase quadrature control. The apparatus may include a pattern generator coupled to the PI and configured to generate a pattern output based on a data signal sampled by the multiphase clock signals. The apparatus also includes a delay-adjust module coupled to the PI and configured to measure timing differences between the edges of a reference clock and the pattern output with adjustable delays. A phase detector is coupled to the pattern generator and configured to detect a phase error between the pattern output and the reference clock. A calibration controller is configured to provide controls to the PI and the delay-adjust module for adjusting delays to the reference clock and the pattern output to calibrate the multiphase clock signals.

Abstract: A multi-functional portable device that connects to and communicates with one or more modular units designed to provide different functionality. The multi-functional portable device of the present invention may communicate with a user computing device. The multi-functional portable device may be employed in various methods and systems used for interacting with and acquiring information from the surrounding environment.

Abstract: A modular device includes base and color sensing portions. The color sensing portion has a face, a controlled light source having a first channel between the light source and the face, and a color sensor arranged at a distal end of a second channel. The color sensor receives light reflected from the target surface and generates output signals representative of a surface color. The first and second channels extend at least 45 degrees apart from each other and respective to the face. The base portion communicates with the color sensor and a user interface enabling control input for the color sensor. The program further receives the output signals from the color sensing device and displays a first image of the detected color, and displays a second image of a user-selected color beside the first image. Color data values are further displayed corresponding to the difference between displayed colors.

Abstract: A pin tumbler lock of a first embodiment includes a shell containing top pins; and a plug, rotatable within the shell, containing standard bottom pins, and a shorter bottom pin, set back from the face of the plug. A tubular key has bitings corresponding to the standard bottom pins, and a projection corresponding to the short bottom pin. When the key is inserted, the bitings and the projection press all the bottom pins to the shear line. In a second embodiment, a lock includes a shell containing top pins and a depression; and a plug, rotatable within the shell, containing bottom pins. The depression is configured and dimensioned to receive one of the bottom pins. The depression may be opposite one of the bottom pins, and there may be one more bottom pin than top pins. When the key is inserted, the bottom pins are moved to the shear line.

Abstract: A multiple dial lock includes reset dials rotatable around a lock shaft. Each reset dial must be at a specific angular position for a user to unlock the lock or reset the combination. Each reset dial has a magnet. A master key includes sensors, each in communication with one signal. Each of the signals indicates to a user that a respective magnet is adjacent a respective sensor, thus assisting a user in recovering a lost combination. A rotary lock includes a dial which rotates a drive cam, which in turn rotates several wheels to their unlocking positions. One magnet for each wheel is provided on the drive cam. Each magnet communicates with one sensor provided on a master key, which also includes signals, indicating that a respective magnet is adjacent a respective sensor, thus assisting a user in recovering a lost combination.

Abstract: Multi-channel IV therapies are achieved through the use of a single source infusion pump, which incorporates three rotary chambers. Each rotary chamber is composed of a base panel with the appropriate cavity for housing a rotor with three sets of rollers, plus tubing defined pathway going into and out of the rotor cavity. Components such as a knob and a sliding latch are incorporated into the inflow and outflow pathways on the base panel respectively to accommodate the installation and removal of anti-free flow disposable IV pump sets. These features also ensures that a properly installed anti-free flow IV pump set will remain secured in the base panel, even when mechanical impulses are experienced by the pump. The chamber tubing of the anti-free flow disposable IV pump set is composed of thin-walled rubber tubing that connects to an inflow stopcock and terminates through outflow clear connector.
