Abstract: An exemplary embodiment, among others, of the present disclosure is directed to a drain closure assembly. A head of the drain closure assembly is fastened to a top end of a stem, wherein a bottom end of the stem is insertable in a drain shoe; and a gasket is fastened around an outer cylinder of the stem below the head. The gasket comprises an upper outer portion and a lower outer portion that each meet at a line that defines a hinge at which the gasket is able to bend, wherein the lower outer portion features a sloped surface from a bottom edge of a rim of the gasket to the line at a top of the lower outer portion, wherein the upper outer portion has a right circular cylinder shape.

Abstract: An exemplary embodiment, among others, of the present disclosure is directed to a drain closure assembly. Such an assembly has a head of the drain closure assembly that is fastened to a top end of a stem, wherein the bottom end of the stem is insertable in a drain shoe. The assembly further includes a gasket fastened around an outer cylinder of the stem below the head. Accordingly, the gasket comprises a series of concentric annular platforms such that a force applied to a top surface of the gasket causes an upper concentric annular platform having a smaller outer diameter to be compressed before the lower concentric annular platform having a larger outer diameter is compressed, thereby creating a seal between the head of the drain closure assembly and the drain shoe.

Abstract: Applicants have created an improved multi-flavor food and/or beverage dispenser including an improved nozzle for injection of flavored liquids into a base liquid.

Abstract: An exemplary embodiment, among others, of the present disclosure is directed to a drain closure assembly. Such an assembly has a domed cap at a top portion of the drain closure assembly and a flange that is positioned below the domed cap. The assembly further includes a stem that extends from below the flange to a bottom portion of the drain closure assembly and a gasket seal that is positioned around the stem at a bottom of the drain closure assembly. The gasket seal has a frusto-conical shape, wherein a top portion of the gasket seal has a wider diameter than a bottom portion of the gasket seal, and the gasket seal has a central circular opening that fits closely around the stem.

Abstract: A multi-functional transport apparatus includes an adjustable ramp capable of being positioned within the existing trunk of the existing motor vehicle, and a collapsible cart selectively positioned on the adjustable ramp. Advantageously, the collapsible cart is at a folded position when positioned on the adjustable ramp. Such a collapsible cart is deployed to an unfolded position when displaced off the adjustable ramp. Notably, the collapsible cart is selectively tilted between a plurality of inclined positions while seated on the adjustable ramp.

Abstract: Disclosed are various embodiments of a linkage assembly apparatus that comprise a spring clip that comprises a first end aperture, a second end aperture, and a connector aperture separated between a number of bending lines positioned along a length of the spring clip. The spring clip can be elastically deformed for insertion of a lift rod through the first end aperture and the second end aperture. The linkage assembly can also include an upper linkage rod that extends in a direction longitudinally. The upper linkage rod comprises a socket at a first end and a snap-on connector at a second end. In addition, the linkage assembly includes a lower linkage rod comprising a ball disposed toward an end of the lower linkage rod and a slot that extends along a length of the lower linkage rod. The slot can be used for connecting with a ball rod of a pop-up drain body.

Abstract: Recently, there has been an increased desire to measure load currents of class-D amplifiers to improve performance. The traditional solution has been to include one or more discrete components in series with the load, but this degrades performance. Here, however, circuit is provided (which includes sample-and-hold circuit) that accurately measures load currents without inhibiting performance and that is not inhibited by the phase differences between the load voltage and load current.

Abstract: A pressure regulator comprising a housing having an inlet port and an outlet port, a linearly sliding member for selectively covering a section of a passage between the inlet port and the outlet port, a diaphragm interconnected to the linearly sliding member to slide the linearly sliding member in reaction to pressure levels in the housing, and a valve seat located in the passage between the inlet port and the outlet port. The linearly sliding member includes a sealing disc for preventing fluid flow past the valve seat. The valve seat is located closer to the outlet port than to the inlet port.

Abstract: A power converter receiving a single-sided supply which is ground-terminated and providing a regulated positive supply and a regulated negative supply that is optimized to the expected output range of a class AB amplifier, as well as providing excellent efficiency. The converter finds application as a compact converter to power an audio amplifier driving an audio device which is ground terminated, such as a speaker.

Abstract: Audio amplifiers and methods of generating audio signals are disclosed. A disclosed example amplifier comprises a first driver to receive a first signal; a second driver to receive a second signal; a configurable signal delivery circuit; and a mode selector in communication with the first and second drivers to selectively configure the signal delivery circuit in a voltage boost mode or a voltage buck-boost mode based on a characteristic of the input signal.
