Abstract: Systems and methods for monitoring life signs in a subject. A radar unit comprising generates raw data and a processor unit receives raw data and identifies oscillating signals in a series of arrays of complex values representing radiation reflected from each voxel of a target region during a given time segment. A phase vaue is determined for each voxel in each frame and a waveform representing phase changes over time for each voxel is generated. Voxels indicating an oscillating signal are selected and life sign parameters are extracted.

Abstract: Systems and methods for providing wide field-of-view radar arrays. Quadrature phase-shift keying (QPSK) beam forming reduces side lobes by applying a phase shift to transmitted signals to selected transmitting antennas. Super-hemispherical radar coverage at high gain in both broadside and end-fire directions is provided by beam directing elements mounted to a printed circuit board.

Abstract: An antenna has a plurality of dielectric layers and a plurality of conducting layers. At least one of the dielectric layers comprises one or more regions with differing dielectric properties. A plurality of such antennas may be arranged in an antenna array. The array includes a radiating component etched in the array top first layer, a reflector embedded in a second layer below the top layer, a feeding network located in a third layer below the reflector, and a ground plane bottom layer configured to shield the feeding network in the bottom layer. At least one of the layers of the array is a non-uniform dielectric layer of a material having a substantially different electrical property compared to the array dielectric and conducting layers.

Abstract: Device for relieving labor pains (DRLP), pains associated with pregnancy and/or menstrual period includes a pressurizing unit, the active face of which is attachable to a user's body facing her sacrum. Harness adapted and arranged to wrap the waist of the user is equipped with stretching stripes providing for urging the tips of pressurizing elements of the pressurizing unit towards targeted sacral foramina. The location of a pressurizing element relative to the back segment of the harness is changeable, thereby a user may adjust it to press against targeted acu-points. The pressurizing elements are rotatable by user's selection. The DRLP is operative in two modes of operation, one of which is the static mode in which the pressurizing elements are kept still. In the dynamic mode the pressurizing elements eccentrically and/or centrically rotate at rotational speeds selectable by the user.

Abstract: A CATV network distributing signals below 860 MHz is modified with a secondary transmission bi-directional capability above 860 MHz by adding filters to separate modified mobile-communications frequencies (above 860 MHz) from typical CATV services (below 860 MHz). CATV subscriber termination points function as extremely localized ultra-miniature cell sites within a building. Multiple cellular networks and possibly multiple providers are simultaneously accommodated over a CATV network. The modified network simultaneously handles traffic in combinations of known cellular air interface standards such as: UMTS, GSM, TDMA, CDMA and PDC. Cellular mobile radio terminals do not have to be modified. Signals traverse on non-utilized CATV frequencies. CATV active elements are modified, and new components are provided. A Cable Mounted Cellular Adapter at the CATV outlet acts as a transmit/receive unit and frequency translator for the cellular signals.
