Granted: 2005-04-05
Abstract: In order to reliably lock an electric plug and socket assembly comprising an outer part and an inner part which can be coupled to the outer part, the inner part is provided with a recess into which, when the two parts are coupled, a snap-on hook means is engaged and maintained so as to act as a spring. When the plug and socket assembly is in a locked position, the snap-on hook means or each snap-on hook means is locked against radial excursion since it rests on a bushing which is axially displaceable on the outer part. In the unlocked position, the backward pulled bush releases the snap-on hook means thereby allowing for disengagement of the outer and inner parts. In order to enable the plugging of the parts when the bushing is in the locked position, the snap-on hook means is provided with two spring legs whose end cam and an inner contour running into the recess of the inner part form a guide for the two leg snap-on hook means.

Title: Improved normalization method for fiber optic sensor system
Inventor: HALL DAVID B
IPC: G01D5/353
Filed: 2000-04-26
Granted: 2005-03-22
Abstract: Quadrature signals Q and in-phase signals I output from a pathlength mismatched interferometric sensor array (10) are normalized by sampling the signals to obtain a first set of values Q k = Q0B k sin .PHI.k corresponding to the sine of the phase shift and a second set of values I k = I0B k cos .PHI.k corresponding to the cosine of the phase shift where k is a running index of the set of consecutive samples of Q and I. A quantity DQ k = (see formula I) is calculated for the quadrature signals; and a quantity DI k = (see formula II) is calculated for the in-phase signals, where u(k) and s(k) are parameters used to determine indices that select specific sampled signals and k is a running index of the set of consecutive samples of Q and I. The normalization factor is then calculated as the ratio R = (see formula III) where Q N = (see formula IV) and I N = (see formula V).

Title: Vehicle location system
Inventor: HILDEBRANT DAVID M
IPC: G01C21/26
Filed: 2000-08-22
Granted: 2003-11-18
Abstract: A system for locating a vehicle using the Global Positioning Satellite System (GPS). The system includes a locator unit and a remote unit. The locator unit is connected to the vehicle and includes a processor; a transmitter for obtaining a location from the GPS indicating the location of the vehicle; and a receiver for receiving the location signal from the GPS for storage in the processor. The remote unit includes a processor; a transmitter for obtaining a location from the GPS indicating the location of the remote unit; and a receiver for receiving the position signal from the GPS for storage in the processor. A device, connected to the processor, generates a request signal requesting the location of the locator unit; and a signal device relays a relative position of the locator unit to a user. Upon activation of the generating device the transmitter transmits the request signal to the locator unit. The locator unit retrieves and transmits the location signal to the remote unit in response thereto. Upon receipt of the location signal the processor of the remote unit compares the location signal to the position signal to determine a relative position of the locator unit with respect to the remote unit. The processor then controls the signal device to indicate the relative position of the locator unit. The signal device provides both an audible and visual indication to the user as to the longitude, latitude and altitude of the locator unit.

Abstract: Tin is added to a zinc cathode target to enhance the sputter efficiency of the target. Films deposited using the cathode, e.g., greater than zero but less than 10 weight percent tin and greater than 90 but less than 100 weight percent zinc improve the chemical durability of a high transmittance, low emissivity coating stack over coating stacks having zinc oxides without tin oxide. High transmittance, low emissivity coating stacks are heated with the heated coating having reduced haze by selecting the thickness of metal primer layer between an infrared reflective film, e.g. a silver film and a dielectric film, e.g., a 52-48 zinc stannate, zinc oxide, tin oxide film or a zinc oxide film. Also disclosed are enhancing films that lower the resistivity of silver films deposited thereon and improve chemical durability of the coating stack.

Abstract: In radiotherapy, a high quality imaging array may be placed after the patient and opposite the radiation source to be used during radiation treatment to verify operation of a shutter system or similar device and/or to compute dose delivered to the patient. A model of the patient may be used and inverted in order to estimate values of energy fluence prior to absorption by the patient and overlapping of the various radiation beams passing through the patient. A test pattern of shutter excitation to illuminate a single ray at a time provides a simple method of obtaining the necessary model. The dose from this test pattern may be subtracted from the subsequent radiation treatment so as to provide limited or no increase in total dose to the patient.
