Abstract: An animal drinking reservoir with replaceable inserts is presented. The animal drinking reservoir with replaceable inserts consists of a reservoir body and a replaceable reservoir insert. The reservoir body serves as a mounting fixture that attaches along a hamster case or any other suitable surface or body. The replaceable reservoir insert is installed along the mounting fixture, where the replaceable reservoir serves as a water dispensing unit suitable for supplying drinking water for animals. Once the reservoir insert is due for a water change, a user can easily swap the spend reservoir insert with a fresh reservoir insert.

Abstract: Whether or not one utilizes direct DC coupling of the microradios to the antenna feed points or couples the RF energy from the dipoles associated with the spaced-apart contact pads on the microradio, in the subject invention one selects only those microradios that are within a certain variance of a preferred direction and then makes sure that the polarization direction of all of these radios is in the preferred direction are identical, in one embodiment by utilizing digital coding, which both activates the microradio and is used to sense the polarity associated with the connection from the signal source to the contact pads.

Abstract: An enhanced duplexer (1) which includes a combination of high dynamic range (HDR) amplifiers (11, 17) and a naovel signal cancellation circuit topology (15). Return signals from the circulator (3) are fed into the first HDR amplifier (11). A portion of the transmit signal is sampled with a directional coupler (7) and amplified with a second HDR amplifier (17) and then combined with the output of the first HDR amplifier (11) using a second directional coupler (13). The gain and phase of the second io amplifier (17) are adjusted so the leakage signals are canceled (19, 21) to enable a radar system to simultaneously transmit and receive signals to and from an antenna with increased sensitivity of operation.

Abstract: A nested cavity embedded loop mode antenna is provided with an ultra wide band response by nesting individual embedded cavity meander line loaded antenna modules, with the meander lines coupled to a ground plane plate either capacitively or directly so as to provide as much as a 27:1 ratio of high frequency to low frequency cutoff. The nested meander line structure is exceptionally compact and eliminates the problem of a null in the antenna radiation pattern perpendicular to the face of the antenna, thus to provide a loop type antenna pattern at all frequencies across which the antenna is to be operated. The use of the nested meander line configuration provides a flush mount for the antenna having a footprint associated with the larger of the meander line cavities and thus the lowest frequency of operation, the nesting precluding the necessity of providing separate side-by-side meander line loaded antennas which would increase the real estate required.
