Abstract: A display surface may include one or more of a top portion including a left section, a right section, and a concave curve between the left and right sections, a bottom portion, including a left section, a right section, and a concave curve between the left and right sections, a vertical distance below the top portion, and a vertical concave surface, between and directly coupled to the concave curve of the top and bottom portions, comprising one or more of a dry-erase surface, a tackable surface, a magnetic surface, and a writeable magnetic surface.

Abstract: A door for a building exterior may include a glass assembly having a height and a depth and a plurality of glass lateral edges, a wood panel, the wood panel being laterally coplanar with and having a same height and depth as the glass assembly, the wood panel having a plurality of wood lateral edges, and a frame that surrounds the glass lateral edges and the wood lateral edges. The frame includes an interior-facing leg, configured to extend from one of the plurality of lateral edges toward an interior portion of the glass assembly and a lateral leg having a lateral leg thickness and orthogonally extending from an edge of the interior-facing leg and facing the lateral edges of the glass assembly and the wood panel, the frame configured so that the lateral leg thickness is the only visible part of the frame when viewed from the building exterior.

Abstract: A handrail connector may include a hollow lengthwise member configured to retain flexibility when empty, a first sleeve having first and second sleeve ends, and a second sleeve having third and fourth sleeve ends. The member has first and second opposing ends and a side surface, the first end having a first hole proximate the side surface, the second end having a second hole proximate the side surface. The first sleeve end couples with the first end of the member and the second sleeve end couples with a first handrail. The third sleeve end couples with the second end of the member and the fourth sleeve end couples with a second handrail. The member is configured to become more rigid when a liquid compound injected into the first hole fills the second hole and hardens.

Abstract: A system may include one or more of a tub that provides tub access to a seated user and includes a top surface, a bottom surface, and a concave well therebetween, a platform that includes water openings extending therethrough, a lift, coupled to a bottom surface of the platform, the lift disposed within the tub and configured to lower the platform within the well, and a plurality of jets around an inner periphery of the well, configured to apply a liquid cleaning solution within the tub in response to the lift and the platform are in a raised position and water has been drained from the well.

Abstract: A generalized method for testing DACs (Digital to Analog Converters) and ADCs (Analog to Digital Converters), such as Sigma Delta (Successive Approximation), Pipeline or Flash ADCs. The DACs and ADCs are tested in pairs using a Digital Tester and on chip test circuitry. The DACs and ADCs may be tested at the highest clock frequency allowed in the specification, shortening test time. The test circuits required for this test scheme comprise cell logic two multiplexer cells and an internal Analog Test Bus. This scheme is extendable to the testing of many DACs and ADCs on the same IC. The number of DACs and ADCs need not be equal. Furthermore, the DACs may have more (or less) bits (addresses) than the ADCs. An ADC may be tested with more than one DAC or vice versa to determine which cell is at fault if a test fails.

Abstract: The present invention provides a window structure which is easily constructed and less expensive to produce than prior art window structures. The window structure includes a metallic sash having an L-shaped cross section which retains an insulated window lite containing a plurality of panes of glass. Glazing tape is placed on the portions of the L-shaped sash which are in plane with the panes of glass and the window lite is seated on one or more setting blocks located on the weight bearing structure of the sash. The window lite is securely mounted to the sash with a silicone adhesive which bonds the edges of the panes of glass to the sash. The silicone adhesive also acts as a thermal break to reduce heat transfer between exterior and interior sides of the window structure. The window structure of the present invention is elegantly simple in comparison to prior art structures since it takes advantage of the inherent rigidity of insulating window lite structures.
