Abstract: A surface cleaning head with dual rotating agitators (e.g., a leading roller and a brush roll) may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The rotating brush roll may be located in the suction conduit with the leading roller located in front of and spaced from the brush roll, forming an inter-roller air passageway therebetween. The leading roller may provide a softer cleaning element than the brush roll and may also have an outside diameter that is less than the outside diameter of the brush roll. The surface cleaning head may also include debriding protrusions contacting the leading roller and/or a leading bumper that extends in front of the leading roller.

Abstract: A robotic cleaner includes a housing, a suction conduit with an opening, and a leading roller mounted in front of a brush roll. An inter-roller air passageway may be defined between the leading roller and the brush roll wherein the lower portion of the leading roller is exposed to a flow path to the suction conduit and an upper portion of the leading roller is outside of the flow path. Optionally, a combing unit includes a plurality of combing protrusions extending into the leading roller and having leading edges not aligned with a center of the leading roller. Optionally, a sealing strip is located along a rear side of the opening and along a portion of left and right sides of the opening. The underside may define side edge vacuum passageways extending from the sides of the housing partially between the leading roller and the sealing strip towards the opening.

Abstract: A handheld wood thread cutting tool with an elongated shank formed with a planar surface and including a first end and a second end with a length substantially longer than its width. The first end has a first wood thread cutting edge aligned substantially in parallel relative to a first vertical plane perpendicular to the planar surface and passing through the length of the elongated shank from the first end to the second end. The second end has a second wood thread cutting edge aligned substantially parallel to a second vertical plane perpendicular to the planar surface and running through the width of the elongated shank from a first side wall to a second side wall. A ball handle is affixed between the first and the second end.

Abstract: A rectenna for high efficiency RF-to-DC wireless energy harvesting that includes an off-center-fed patch (OCFP) antenna and a rectifying circuit. The input impedance of the antenna may be tunable and directly conjugate matched to an impedance of the rectifying circuit over a wide range of frequencies and/or under different operating conditions. An impedance matching network required by rectenna systems may therefore be eliminated using the methods disclosed for the design and implementation of the OCFP rectenna. The OCFP rectenna offers consistently high RF-to-DC power conversion efficiency over a wide range of frequencies and under different operating conditions.

Abstract: Aspects of the present invention are generally directed to impedance spectroscopy in an active implantable medical device (AIMD) comprising a component with one or more electrodes. In an embodiment, the AIMD applies a signal at a plurality of frequencies using one or more of the electrodes. Measurements are then obtained for the applied signal to determine impedance(s) at the applied frequencies of the tissue in which the electrodes are located.

Abstract: A removable rack for holding and/or transporting kayaks with a vehicle such as a pick up, trailer, utility vehicle or flat bed truck. The rack comprises a frame which holds at least one kayaks in a pickup at a selected height and leaving storage room under rack frame. The rack also can be disassembled into a relatively small bundle of parts for easy storage and transport. The rack provides a dolly or hand truck including a frame with wheels and a handle means to maintain the desired spacing between the support surface and the kayak supported by the elevated platform. The hand truck assembly are configured to be easily moved onto an elevated platform, for example, the bed of a truck or an elevated floor such as a raised patio or deck floor. The transport device facilitates transportation of the kayak to a body of water.

Abstract: This method of determining an intracochlea tissue impedance comprises using at least two stimulating electrodes to apply an electrical stimulus to intracochlea tissue. A voltage caused by the stimulus is measured between two measuring electrodes distinct from the stimulating electrodes. From the voltage a stimulus-response characteristic of tissue between the two measuring electrodes is determined. This allows the tissue/electrode interface impedance and potential and the tissue impedance and potential to be uniquely determined. In turn, modiolus currents can be estimated in monopolar stimulation mode. Also provided is automated initiation of re-mapping of the device when tissue characteristics change.
