Abstract: A gas-actuated reciprocal drive apparatus has a double-acting piston in a pneumatic cylinder having a chamber at each end. Gas from an area of higher pressure in a compressed gas system flows into a first chamber, while the second chamber is in fluid communication with an area of lower pressure in the gas system. The piston moves toward the second chamber, purging gas therein back to the lower-pressure area in the gas system, without any venting to the atmosphere. A four-way gas valve reverses the piston motion after each stroke, by reversing the chambers' gas connections. The piston has a pair of circumferential seals, plus a differential shuttle valve that allows gas from the lower-pressure chamber to enter the annular space between the seals, such that the pressure differential across the seals always equals the pressure differential between the two chambers, regardless of the actual pressures in the chambers, thus reducing friction forces on the piston seals, increasing the power output of the apparatus, and extending the service life of the seals.

Abstract: The ability to combine multiple audio signals captured from the microphones in a microphone array is frequently used in beamforming systems.  Typically, beamforming involves processing the output audio signals of the microphone array in such a way as to make the microphone array act as a highly directional microphone. In other words, beamforming provides a "listening beam"  which points to a particular sound source while often filtering out other sounds. A  "generic beamformer," as described herein automatically designs a set of beams (i.e., beamforming) that cover a desired angular space range within a prescribed search area. Beam design is a function of microphone geometry and operational characteristics, and also of noise models of the environment around the microphone array. One advantage of the generic beamformer is that it is applicable to any microphone array geometry and microphone type.

Abstract: A platform for training and aiding a pet to use a conventional toilet is attached to the rim of a toilet bowl and further provided with a holding means used for holding a tray containing a substance to attract and create a habit for the pet to come to that location. Instead of a tray, a specially designed unit containing cat litter ar its equivalent can also be used for the same purpose. Over time, the holding means can be removed as the pet no longer needs to be « baited » to the location. In this manner, only the holding means and tray become useless, a far lesser investment.

Abstract: A directional hearing aid (100) comprising at least two microphones (201, 202) has means (200) for matching differences in amplitude and phase between the two microphones (201, 202). The microphone matching means (200) compare differences between measured transfer functions of the microphone signal paths at a number of frequencies during use of the hearing aid (100), compares the differences to differences at similar frequencies in a model of the transfer functions of the microphone signal paths, derives a set of parameters based on the comparison, and adjusts the parameters in order to minimize the difference in level differences between the model and the microphones (201, 202). The model is then used to match the microphones (201, 202) mutually by applying appropriate control parameters (103, 104, 105, 106) to an adaptive matching filter (108) carrying one of the microphone signals.
