Abstract: A wireless telephone having a first directory having assigned memory locations with indicators associated therewith. Telephone numbers are stored in the respective memory locations. A speed dialer places a call to one of the telephone numbers stored in the memory locations of first directory upon entry of the indicator associated with the memory location. The wireless phone has a second directory and a sorting unit to order telephone numbers according to parameters associated with the telephone number, the telephone numbers are stored as ordered in the second directory. There are alphanumeric identifiers associated with the numbers stored in the second directory. The wireless phone has a telephone display, and a scroller allows the user to scroll up and down through the numbers stored in the second directory to sequentially view the alphanumeric identifiers associated therewith on the telephone display. The wireless telephone also has a function setting device for setting a plurality of parameters.

Abstract: A threaded fastener and mating driver system is used to apply a uniform torque to the entire fastener body and thereby facilitate removal of stuck fasteners. The driver tool is a two stage driver with one stage driving the inner bore of the fastener and the second stage driving the fastener head. The two driver stages are linked via a series of pins, each pin acting as an individual lever, such that the two drivers apply torque equally to the fastener. The entire driver assembly is housed in a block which can be attached to a standard ratchet or driving tool. The fastener is designed to be installed using a single stage screwdriver and normally has a foil seal covering the bore drive portion of the fastener. If the fastener becomes stuck, the foil seal is broken and the two stage drive system, including a bore driver and a screw head driver, is inserted into the fastener to effect additional removal torque.

Abstract: A method and apparatus for enhancing an image for a display, first digitizes the image to produce a map of the image, this map containing pixels having 2.sup.n grey levels where n is the number of bits per pixel. The map of the image is then downsampled to produce a downsampled map of the image. Thresholding is then performed on the downsampled map of the image to reduce the number of bits per pixel from n bits to m bits to produce a thresholded downsampled map of the image, where m is less than n. The number of bits per pixel is restored from m bits to p bits, where p is greater than m, to produce a restored thresholded downsampled map of the image. The restored thresholded downsampled map of the image can be downsampled again to produce an image map suitable for display on a low to moderate cost display, such as a CRT, with grey scale capability. The displayed image has an enhanced appearance, since it is high fidelity with respect to the original.

Abstract: A camera is used in combination with a photographic flash device and a delay mechanism for controlling the time when the camera shutter will open. A flash device on a camera generates a preliminary flash in synchronism with the depression of the camera's body release to induce the eyes of the subject to blink. A delay period is also initiated in the camera's controls to delay opening of the shutter. The duration of this delay is such that an exposure is not likely to be made until the refractory period after the evoked involuntary blink has been completed. At the end of this delay period, the shutter is allowed to open and a second flash may be generated to provide supplementary illumination. The camera may be an auto-ranging camera wherein camera-to-subject distance is determined electronically prior to opening of the shutter by sensing light from the preliminary flash, which has been reflected by the subject back to a sensor in the camera.
