Abstract: An integrated circuit (IC) package testing apparatus integrates a temperature sensor, heater (or cooler), and controller within a single modular unit. The controller is a microprocessor embedded within the modular unit and in communication with the sensor and heater. The controller allows a selected testing temperature to be input by a user via a communications link to the controller. Each IC package has its testing temperature individually controlled by a controller. The module is easily attached and removed from an open-top socket through the use of latches on the testing socket. Many IC packages can be quickly placed and removed from testing sockets when a matrix of sensors and heaters (or coolers) are located on a single top attach plate with the sensors and heaters (or coolers) individually spring-loaded on the single top attach plate.

Abstract: A body-mountable display system having a first structure for receiving an input signal and producing a video output in response thereto, a garment wearable by a user, and a second structure for operatively connecting the first structure to the garment to allow the first structure to be universally repositionable relative to the garment. The first structure includes a hand-holdable portable display including a housing having a viewing aperture for viewing the video output. The second structure includes a flexible element having spaced ends with one end mounted to the garment and the other end including a structure for detachably mounting the portable display to the flexible element. The portable display may include a portable virtual image display for focusing the video output at one of (a) infinity and (b) a desired finite distance viewable by an observer. The body-mountable display system may include, in combination, a computer producing the input signal.

Abstract: A binocular head mounted display unit utilizing a single display and binocular optical system is shown for projecting an enlarged image of displayed information in the direct line of sight and central field of view of each of the user's eyes, while maintaining the user's peripheral vision free from obstruction to allow the user to selectively focus on the virtual image or not. The binocular optical system directs the user's eyes inward at an angle that is natural for a person viewing an object at a distance that is less than infinity. Further, the binocular optical system automatically compensates for variations in the interpupillary distances of various users, wherein those variations may be as great as one inch. This head mounted display unit is suitable for a variety of applications, including virtual reality applications, as well as a display for a compact portable computer.

Abstract: A head mounted display system is shown that is modular such that various components of the system are removably mounted and/or adjustably mounted on a frame that is supported on a user's head. The head mounted display system can thus accommodate different users and components of different configurations. In particular, the display system includes a mirror through which a displayed image is viewed, the position of the mirror being adjustable and the mirror being removable from the frame of the display system. The display system further includes a nose piece that is adjustably mounted on the frame so as to allow the distance between the frame member supporting the display and a nose bridge to be varied. The nose piece is further completely removable from the frame of the display system so as to allow the display system to accommodate a user wearing conventional glasses. The display system also includes removable earphones and removable earphone retainers disposed on the temples of the display system.
