Abstract: A system and method for creating and retrieving coupons using an electronic coupon database includes registering coupons with the database by a vendor, and then registering cell phones, also with the database; so that cell phones subsequently can request coupons from the database. The coupons are encrypted and sent to the requesting registered cell phone, which then decrypts the coupons for display and redemption at a point of sale. Provision is made to prevent the transfer of coupons from the requesting cell phone to some other cell phone in the system.

Abstract: A translator is provided for reading the bar codes displayed on the screen of a portable electronic device which utilizes a digital camera and/or a microphone responsive to tones from the portable electronic device to process and convert the information received from the camera and/or the microphone to a form readable by a reflective bar code reader without requiring any modification of the bar code reader.

Abstract: A vehicle washing system is mounted adjacent the ceiling of a garage or other structure. It includes an upper frame and a mat is located beneath the frame for catching and draining off fluids used during the washing operation. After a vehicle is driven onto the mat beneath the frame, a mechanism is operated to lower a waterproof curtain from the frame down to a point adjacent the mat to completely surround the vehicle. In addition, fluid conduit rings also are lowered from the frame to various positions surrounding the vehicle. Nozzles in these rings are directed toward the vehicle location and washing and rinsing fluid is supplied, under pressure, to the rings in a pre-established sequence to effect the washing of the vehicle. In addition, hot air drying tubes and nozzles are lowered from the frame when the device is in use to permit the application of hot drying air to the vehicle after the washing cycle has been completed.

Abstract: A magnetically enhanced membrane switch operator is constructed with a rigid ferromagnetic base plate. This base plate is spaced from a rigid ferromagnetic cover plate, which has an opening through it. A resilient flexible membrane sheet is suspended between the base plate and the cover plate, and is located in close proximity to the cover plate. The sheet carries a circular magnetic disk which, in the rest condition operation of the switch operator, is adhered by magnetic attraction to the cover plate. To operate the switch, sufficient force to overcome the magnetic attraction between the magnet and the cover plate, along with the force required to distort the resilient membrane sheet, is used to move the sheet toward the base plate. When the membrane sheet is moved into close proximity to the base plate, magnetic attraction between the base plate and the magnet facilitates closure of the switch at the end of its travel.

Abstract: A method and system for controlling the operation of a digital computer system having a memory, visual display, and keyboard employs software for displaying a graphical user interface (GUI) in the form of representations of successive tasks. This display is effected in a format which contains, in part, an unchanging representation of at least a core plurality of the keys of the keyboard used with the digital computer system. This representation is displayed in the same arrangement used on the keyboard. The GUI then further indicates within the unchanging representation of the core plurality of keys, a dynamically changeable function representation of the functions to be performed upon operation of the corresponding one of the displayed keys. This changeable function representation changes in a hierarchal sequence in response to successive operations of selected ones of the keys, as indicated on the visual display of the GUI.

Abstract: An ergometrically improved keyboard data input device particularly suited for computers includes a housing adapted to underlie the palm of the hand of an operator in a relaxed, natural, concave position; so that the fingertips of each finger extend substantially vertically downward through an aperture in the top of the housing. Data input keys are mounted on a data input key support member located inside the housing, beneath the aperture. The keys are arranged in groups of data input keys in three dimensional patterns at each of the fingertip positions of the hand of the operator. The device includes a provision for raising and lowering the key support member within the housing, relative to the aperture. Actuators also independently move the opposite ends of the key support member back and forth within the housing, relative to the aperture, to adjust the locations of the groups of keys relative to the portion underlying the palm of the hand of a user to compensate for hands of different sizes.
