Abstract: A system for providing a thermal transformer to provide heating and cooling to enclosed structures, most generally a building using solar power combined with geothermal storage and a heat powered heat pump to raise or lower the temperature of the stored energy to a useful temperature as needed. The system also has an electrical generation embodiment to provide electricity in addition to the heating and cooling. The system will collect and store solar energy and supply heated or cooled water to the building's existing HVAC system while consuming no fossil fuels and emitting no greenhouse gases. The system may also be used in one embodiment to supply power for the pumps/fans used to circulate the heated or cooled air or water throughout the building.

Abstract: A surgical apparatus for use with a prosthetic holder to which a prosthesis is secured by sutures. The apparatus includes an elongated handle having a grip end and a coupler end and defining a first aperture extending along a length from the grip end to the coupler end. The apparatus can also include a first shaft at least partially disposed within the first aperture with a first actuator at the grip end and a holder coupling mechanism at the coupler end. The apparatus can have one of a second shaft and a sheath disposed along the handle with a second actuator at the grip end and a cutting element at the coupler end. A force applied to the first actuator enables one of engagement and disengagement with the prosthesis holder, and a force applied to the second actuator enables deployment of a cutting element to cut the sutures securing the prosthesis to the prosthetic holder.

Abstract: A method and apparatus for identifying a missing person, in particular, a missing child, includes utilizing a CD or other electronic storage medium to store unique identifying indicia of the person, portions of which are encrypted to protect sensitive information and to make it accessible only to authorities having been given a decryption key in advance. The CD or other storage medium is held by the legal guardian of the person, i.e. child, and given to authorities only if the child goes missing. Sensitive personal information is never centrally stored in a database. A kit, including the CD, may also include a conventional photo ID card of the child and, optionally, a booklet of instructions to the parent or other legal guardian.

Abstract: An improved apparatus and system for hangers which automatically space themselves from one another such as to regulate the space between garments. These hangers have a spacing post protruding laterally from below the intersection of the hook and apex of the hanger body. The spacing post can be formed as part of the hanger, or added to existing hardware. This invention has the advantage of allowing clothing to be cascaded to allow the viewing of various ensembles. This invention also has the advantages, in certain embodiments, of being removable.

Abstract: A new drum design with acoustic advantages. The design can also be used for use in drum kits that allow for closer spacing of the geometric centers between drums with a given area of drum head. This solution also provides for an increased tangential proximity between adjacent playing surfaces to reduce rim clicks. A further advantage is a large sweet spot for tone while still maintaining a wide range of tonal variation by playing in the corners.

Abstract: A touch-sensitive semiconductor chip having a physical interface to the environment, where the surface of the physical interface is coated with a fluorocarbon polymer. The polymer is highly scratch resistant and has a characteristic low dielectric constant for providing a low attenuation to electric fields. The polymer can be used instead of conventional passivation layers, thereby allowing a thin, low dielectric constant layer between the object touching the physical interface, and the capacitive sensing circuits underlying the polymer.

Abstract: A finger imaging system for receiving the finger of a person being fingerprinted by an automated fingerprint reader. The system includes a finger imaging device having a finger receiving portion for receiving the finger to be fingerprinted. Extending outward from the finger receiving surface is a locator bar that is located to engage a crease of the subject finger when it is in approximately the desired position. The locator bar may be fixed by or movably attached to the finger receiving surface, or may protrude through the finger receiving surface, possibly being attached to an interior movement mechanism. The locator bar may clean the finger as it is being positioned, and may include sensors for sensing non-image information to verify the legitimacy of an offered finger. The locator bar may also include a shunt for diverting unwanted static electricity stored on the finger before it is positioned for fingerprinting.

Abstract: A finger imaging system for receiving and holding a finger of a person being fingerprinted by an automated fingerprint reader. The system includes a finger imaging device having a finger receiving portion and a finger positioning portion, together forming a recess of reducing dimension such that a subject finger forceably inserted into it is held in a stable position. The finger positioning portion may have a flexible or resilient surface contacting the finger to enhance the stabilizing effect. The flexible surface may be inflated to increase the retaining pressure.

Abstract: A capacitive fingerprint sensor includes a polymeric protective coating defining a sensing surface and having conductive particles suspended therein. The conductive particles act as parallel strings of series capacitors to couple the capacitance the fingerprint-bearing skin of a user's finger applied to the sensing surface to capacitive sensing elements beneath the protective coating. The polymeric material of the coating is durable and scratch resistant. The conductive particles enable use of a protective coating of 10 to 20 microns in thickness while providing a high degree of sensitivity and image resolution.

Abstract: Minute surface damage or irregularities on the sensing surface of a capacitive sensor integrated circuit is detected by acquiring a preliminary image of the capacitance readings for the sensor array, coating the sensing surface with an electrolyte solution, then acquiring an additional image while the sensing surface is coated and/or after the electrolyte solution is removed. The electrolyte solution accelerates manifestation of pixel degradation or failure caused by surface damage or irregularities. Defective regions are identified by change of grayscale pixels in the preliminary image while the electrolyte coating is on the sensing surface and then again after the electrolyte coating is removed.
