Abstract: A portable computer has the features and benefits of a conventional portable computer and in addition including the added features of two larger than normal speakers, an integral microphone, a infrared transceiver and a touchscreen. The computer, also, has ports for receiving components tailored for disabled personnel including switching ports. The portable computer has a housing with an upper assembly and a lower assembly. The lower assembly has a support rib projects upward from the base and extends from one of the side walls towards the center of the lower assembly. One of the side walls has a reinforcing bar extending from generally the support rib to the front wall. A battery opening is defined by the reinforcing bar, one of the side walls and the front wall. The lower assembly defines a quadruplet of quadrants. The computer has a battery for powering the computer located in a quadrant, the battery quadrant. A hard drive and the power board are in the quadrant adjacent the battery quadrant.

Abstract: An apparatus is provided for loading and/or unloading wafers from a holding cassette to a quartz boat without scraping the wafer on the slots contained in the quartz boat; the apparatus comprising a robot and a paddle. The improvement resides in the main feature of wafer sensor means disposed on the surface of the paddle, the wafer sensor means being connected to a microprocessor which converts and digitizes an analog signal from the wafer sensor means, the analog signal indicating the position of a wafer disposed on the surface of the paddle. Further included is an arrangement for signaling the robot to compensate for the particular position of the wafer on the paddle by adjusting the position of the paddle with respect to the quartz boat.
