A refrigerator drawer assembly includes a pan support that includes a wire member that has a first side and a second side. A first bracket is coupled to the first side using a first coupling system. A second bracket is coupled to the second side using a second coupling system different than the first coupling system. The second bracket is substantially identical to the first bracket.

An interactive, handheld apparatus is provided. The apparatus includes a housing, a display screen on the housing, an electronic position location system, a stylus for selecting images on the display screen, a directional control pad on the housing and a memory device. The electronic position location system includes a processor that is capable of determining a location of a selected region of the display screen. The memory device includes computer code for an educational game and is operatively coupled to the processor. A light is associated with the stylus. The light is illuminated to indicate that the stylus is available for use during operation of the educational game.
摘要:
Disclosed herein is a sensor system having a sensor and at least one communication line operable with the sensor. The transmission medium is configured to convey data transmitted by the sensor to a remote location. The sensor transmits data on the communication line a plurality of times by at least two methods of transmission or modulation. Further disclosed herein is a method based on the foregoing. Further disclosed is a method of communicating by modifying a voltage amplitude of a signal and receiving the communication signal by employing a variable threshold detection circuit in the downhole device. Further disclosed is a system for communicating data between a downhole device and a remote location including a remote device for generating a communication signal, the remote device configured to modify a voltage amplitude of said communication signal.

A printer capable of transferring images to different types of media is disclosed. Media sheets of different sizes and types may be dispensed through a single input path to a print station including a printhead and a platen. The printhead is adapted for transferring images to media using either a direct thermal or dye diffusion process. A capstan roller, platen roller, picker assemblies and kicker assemblies are driven by a single motor, allowing for substantial cost and space savings. Other features are directed to improving the quality of images using the direct thermal and dye diffusion processes.
摘要:
A materials system in which exchange coupling is achievable has the potential for allowing direct overwriting of data and comprises at least two multilayer films of platinum and cobalt with independently controlled coercivity and Curie temperatures.
摘要:
Pt/Co multilayer materials systems having a thin metal interlayer possess superior room temperature coercivity, a square polar Kerr hysteresis loop, sufficient polar Kerr rotation, and are suitable for magneto-optical recording. These material systems allow the reading and writing of information from the substrate side of the multilayer film.
