Abstract: A medical device includes wake circuitry and telemetry circuitry. The wake circuitry is configured to receive a first set of data from a device associated with the medical device, where the first set of data is received at a frequency band. The wake circuitry is configured to output a set of pulses based on the first set of data. The wake circuitry is configured to detect a data pattern using the set of pulses. The wake circuitry is configured to output an activation signal in response to a determination that the data pattern satisfies a data pattern requirement. The telemetry circuitry is configured to output a second set of data in response to receiving the activation signal. The second set of data is transmitted at the frequency band. The telemetry circuitry is configured to establish a communication session with the device using the second set of data.

Abstract: A computing device retrieves a stabilized weight and a weight-based item count for one or more items to be purchased. Responsive to retrieving the stabilized weight, the computing device retrieves an image-based item count and an expected weight based on the image-based item count for the one or more items to be purchased. The computing device selects between authorizing and blocking checkout of the one or more items based on the weight-based item count, the image-based item count, the stabilized weight, and the expected weight.

Abstract: Disclosed is a hermetic AC electric motor that includes harmonics shunting such that high frequency harmonics are shunted from the AC electric motor without the use of one or more high frequency filters in the associated motor drive. A related method of operating an AC electric motor includes shunting high frequency harmonics to a fluid passing through the AC electric motor. Also disclosed is a simplified variable speed motor drive system which eliminates the need for a filter for removing high frequency harmonics.

Abstract: A multi-sensor system (10) for detecting the presence of objects on the surface of the ground or buried just under the surface, such as anti-personnel or anti-tank mines or the like. A remote sensor platform (12) has a plurality of metal detector sensors (22) and a plurality of short pulse radar sensors (24). The remote sensor platform (12) is remotely controlled from a processing and control unit (14) and signals from the remote sensor platform (12) are sent to the processing and control unit (14) where they are individually evaluated in separate data analysis subprocess steps (34, 36) to obtain a probability "score" for each of the pluralities of sensors (22, 24). These probability scores are combined in a fusion subprocess step (38) by comparing score sets to a probability table (130) which is derived based upon the historical incidence of object present conditions given that score set.

Abstract: An automatic electroplating machine has a plurality of plating barrels supported by cantilever arms on an elevator-conveyor for intermittent movement along a continuous, generally horizontal path to and through a plurality of work stations. Groups of barrels are lowered into and lifted out of a series of treating tanks located at work stations and along a rectilinear portion of the conveyor path. When the barrels are in lowered positions pinions on some of the barrels are engaged with reciprocally movable rack assemblies which oscillate the barrels in unison about horizontal axes and within the associated treating tanks.

Abstract: A power unit having an endless belt immersed in a tank of water and disposed on upper and lower rotatable rollers in parallel alignment tightly enough to frictionally engage and rotate the pullies, there being transversely arranged and longitudinally spaced, relative to the belt, collapsible air buckets or air traps on the outwardly facing side of the belt. When operating, the belt has one part continually moving upwardly and an opposite part moving downwardly. The air buckets open downwardly and expand on the upwardly moving part of the belt; and those on the opposite downwardly moving part open upwardly in a collapsed condition. Air is pumped to a horizontally disposed discharge pipe adjacent the lower end of the belt, the pipe having openings for discharge of air into the succeeding lower open buckets to cause the buckets to be filled with air and expand the buckets so as to move buoyantly upwardly.

Abstract: Method of recovery of crude oil from oil bearing formations and/or sands especially where the oil in such formations have been partly exhausted or depleted and will flow into the wells drilled into such formations at a very slow rate or not at all due to the high degree of viscosity of the oil. The method comprises thinning the crude oil in the formation by introducing into the oil well a thinning fluid, such as a solvent or mixture of solvents that will flow into the formation and thin the oil in the formation sufficiently so that it will flow into the well. A further step is heating the solvent either before the solvent is introduced into the well or after it is in the well and pressurizing the well to increase the penetration of the solvent into the formation. One method of heating the solvent in the well is to introduce water into the well, allow the solvent to rise to the surface of the water and introduce sodium into the well to cause a reaction with the water for producing heat and pressure.

Abstract: A projectile having mainstream air flow directed to its surface region of rmal air non-attachment during operational flight and in which drag frictional forces in the laminar flow boundary layer region are minimized to produce maximum range. The projectile conical nose has a forward air intake nozzle in fluid communication with a plurality of internal passageways that terminate in outlet ports circumferentially spaced along the rearmost edge of the nose member adjacent the forwardmost external or lateral surface of the projectile main body portion.
