Abstract:
An electrical connector housing with a latch structure is provided. The latch is releasably engageable with corresponding structure on a mateable electrical connector housing. The latch structure resiliently and deflectably extends from the electrical connector housing. At least one rib extends from the surface of the electrical connector housing adjacent the deflectable end of the latch structure to prevent fishhooking of cables or the like into the space between the latch structure and the housing. The rib for preventing such fishhooking is further engageable with the latch structure to prevent overstress. Side walls disposed in spaced relationship to the latch structure may further prevent overstress and fishhooking.
Abstract:
An electronic watch includes a "traveler's time" function which can be activated when a wearer leaves on a long trip, east or west by plane, boat or the like. This function will advance or retard the operation rate of the watch so that after a user-determined trip time has elapsed, the watch will display the actual local time at the arrival location, and the watch will resume operation at its normal rate. By glancing at the watch from time to time, a traveler can become accustomed gradually to a time change caused by his travel through different time zones so that the psychological effects of "jet lag" are minimized. The watch includes a microprocessor (10), a quartz crystal (20) for providing a time standard, a display (30) for displaying the time, and a set of switches (40-90) for activating the watch's functions. The microprocessor includes a set of registers (145 to 160) for storing the departure, destination, and traveler's times, and for controlling operation of the watch.
Abstract:
An apparatus and method for aiming vehicle headlights and for visually displaying the illumination patterns of vehicle headlights. The apparatus focuses the light beam on a screen and includes a video sensor for sensing the intensity of the light in each cell of a matrix of cells overlying the focused light beam and for generating an electrical signal for each cell indicative of the position of the cell and the intensity of the light beam in each cell and a computer for comparing at least some of the electrical signals to each other and with established criteria to determine whether the headlight is aimed within a prescribed degree of accuracy. The same apparatus may be used to describe the illumination pattern of a headlight by visually displaying at least some of the electrical signals, i.e. the light intensities and their locations, for example on a printer or CRT. The conformance of headlight aiming and illumination to established standards can be easily determined by including steps in the computer software to apply the applicable criteria. The aiming conformance tests may produce error signals for controlling powered screwdrivers to correct errors in aiming. The apparatus preferably includes a centering indicator for centering the headlight relative to the lens by comparing electrical signals produced by discrete light intensity sensors disposed around the periphery of the lens.

Abstract:
A trailer light connection system includes T-shape connectors principally for truck lighting systems respectively having three terminals including a modularized tap plug, split wire connectors principally for automobile lighting systems respectively including a modularized plug and trailer wiring harnesses respectively used with either the T-shape connector or the split wire connector and having a modularized plug interconnecting therewith. By standardizing the system components and modularizing the plug connections, the trailer lighting system of the present invention reduces the number of stock keeping units required while simplifying system installation.
Abstract:
A core holder for use in the testing of a geologic core sample or other similiar cylindrical sample. An elastic rubber sleeve for receipt of a core sample is disposed in an open-ended, cylindrical cavity of an open-ended, cylindrical body. The ends of the sleeve are fitted over flanged ferrules. A cylindrical end plug is releasably locked in one end of the body with one of its ends inserted through the adjacent ferrule engage one end of the core sample. A cylindrical piston housing having a cylindrical cavity is releasably locked in the other end of the body. A cylindrical piston is disposed in the cavity of the piston housing with one of its ends protruding from an open end of the cavity and inserted through the adjacent ferrule to engage the other end of the core sample. Pressurized fluid moves the piston to apply axial force to the core sample. The sleeve is compressed by pressurized fluid to apply radial force to the core sample. Test fluid conduits are provided in the piston and the end plug.
Abstract:
A hand-held ice scraper having an elongate handle portion and a blade attached to one end thereof. The scraping blade is substantially J-shaped and comprises dual outwardly flared scraping arms, one of which is longer and wider than the other. One of the scraping arms has a scraping surface with a smooth, beveled edge while the other features a scraping surface having a plurality of elevated ridges, each ridge having a beveled edge. The blade is firmly secured within the handle portion, preferably be an interference fit.In one embodiment the scraper has a selectively operable illumination means mounted within the handle portion. The illumination means is adapted to direct light through a translucent blade.
Abstract:
A direction-finding interferometer (100) includes a novel autocalibration subsystem using bi-directional transmissions at a common frequency. The interferometer determines direction using a primary phase comparator (15) to assess the phase differences in signals transmitted by signal channels (13) from multiple antennas (11). The signal channels may include RF amplifiers (17), mixers (19) coupled to a local oscillator (23), IF amplifiers (21), and transmission lines.The autocalibration subsystem employs a frequency synthesizer (25) as a calibration signal source. The calibration signal path is directed between reversing switches (40) and couplers (33) in alternating directions via transmission lines (57 and 59). In either direction, the calibration is split so that part of the signals are coupled into the signal channels, and the remaining part is directed to a secondary phase comparator (131). The outputs of the primary and secondary comparators provide the data necessary for autocalibration.Other embodiments provide for a secondary comparator operating at a frequency range similar to that of the primary comparator. Gain autocalibration is also described.
Abstract:
The present invention relates to novel propagated apple trees having increased vole resistance and to methods for propagating such trees; and relates in one aspect to an apple tree having a vole-resistant rootstock and having growing thereon a desired apple bearing scion. In a preferred embodiment, the vole-resistant rootstock has a characteristic modifying distinct interstem interposed between the apple bearing scion and the rootstock. In another embodiment of the invention, the stocksystem is a composite stocksystem wherein a portion of the stocksystem is of a variety (seedling or other rootstock) distinct from the vole-resistant stock and wherein the portion of the rootstock above ground and to which the scion or interstem is grafted, comprises the novel vole-resistant stock. The nature of the companion rootstock is not critical and any compatible rootstock such as those already known in the art, for example, from "Delicious seedlings" can be employed. The systems proposed in the present invention present apple trunk tissue to voles which is unpalatable to them.
