Abstract: An electrical circuit includes circuitry connected to a dry contact switch. The circuitry translates an open or closed state of the dry contact switch to a current loop current having one of multiple current levels, where the multiple current levels comprise a first non-zero current level and a second non-zero current level that is different than the first non-zero current level. The circuitry further sends the current loop current, at the one of the multiple current levels, via a current loop connected to the electrical circuit.

Abstract: A device includes a device input, an output connector configured to connect to a current loop, and current loop transmitter circuitry. The current loop transmitter circuitry receives, via the device input, an input from a dry contact switch, and translates a state of the dry contact switch to a current loop current. The current loop transmitter circuitry transmits the current loop current via the output connector through the current loop.

Abstract: An inflatable pool cover for pool apparatus, including hot tubs and spas, is disclosed. The inflatable pool cover includes a body having slightly larger diameter than the pool apparatus. The body, made of durable and waterproof material, includes rings, handles and a valve. Rings are used to tie the inflatable pool cover to the pool apparatus via straps. Handles are used to place or remove the inflatable pool cover from the top of the pool apparatus. The valve is used to inflate the body. In one example, the body has a tapered portion. When placed over the pool apparatus, the tapered portion of the inflatable pool cover ensures water and debris slide and fall outside of the pool apparatus, preventing accumulation of water and debris over the inflatable pool cover. For easy storage and transportation, the inflatable pool cover may be deflated, folded and stored in the included kit.

Abstract: Certain examples involve a circadian effect light fixture. The circadian effect light fixture includes a controller to receive a modifying factor based on a circadian impact profile. The modifying factor includes an indication of an intensity value, a correlated color temperature value, and a color value over a range of time. The circadian effect light fixture also includes a first lighting element controlled by the controller to produce a first light output having a first intensity, a first correlated color temperature, and a first color value. Further, the circadian effect light fixture includes a second lighting element controlled by the controller to produce a second light output having a second intensity, a second correlated color temperature, and a second color value. A combined light output of the first lighting element and the second lighting element tracks the modifying factor over the range of time.

Abstract: Silicone-containing light fixture optics. A method for manufacturing an optical component may include mixing two precursors of silicone, opening a first gate of an optic forming device, moving the silicone mixture from the extrusion machine into the optic forming device, cooling the silicone mixture as it enters the optic forming device, filling a mold within the optic forming device with the silicone mixture, closing the first gate, and heating the silicone mixture in the mold to at least partially cure the silicone. Alternatively, a method for manufacturing an optical component may include depositing a layer of heat cured silicone optical material to an optical structure, arranging one or more at least partially cured silicone optics on the layer of heat cured silicone optical material, and heating the heat cured silicone optical material to permanently adhere the one or more at least partially cured silicone optics to the optical structure.

Abstract: Certain examples involve controlling a circadian impact of a lighting system. For instance, a lighting system includes a first lighting fixture. The first lighting fixture includes at least one lighting element to illuminate a first space and a first controller to control a first light output of the at least one lighting element. Additionally, the lighting system includes a first background circadian system that provides a first modifying factor to the first controller of the first lighting fixture. The first modifying factor is associated with a first circadian impact profile that specifies a first circadian impact level in the first space. Further, the first controller of the first lighting fixture controls the first light output based on the first modifying factor.

Abstract: According to one embodiment, a protective device for use in congestive heart failure treatments, and other treatments, includes a control mechanism, an elongate shaft, and a protective plate. The control mechanism is coupled with a proximal end of the elongate shaft and the protective plate is pivotably coupled with a distal end of the elongate shaft. The elongate shaft enables the protective plate to be inserted within a body and navigated distally of a heart wall. The protective plate has a relatively wide and thin body portion and is pivotable relative to the elongate shaft by operation of the control mechanism. Pivoting and/or navigating of the protective plate within the body allows the protective plate to be positioned adjacent the heart wall to shield body organs or tissue surrounding the heart wall from being damaged by surgical instruments inserted through the heart wall.

Abstract: A light fixture includes a flexible shroud, an outer housing, and a light source within a light engine. The light engine couples within the outer housing so as to define a gap between the light engine and an inner perimeter of the outer housing. The flexible shroud forms at least first and second edge portions. The light engine couples with the first edge portion, and the inner perimeter of the outer housing couples with the second edge portion, so that the flexible shroud covers at least part of the gap. A shroud for a light fixture may include a flexible shroud that defines one or more edges. The shroud may include one or more coupling features along the one or more edges. The flexible shroud may form a thickness variation at the coupling feature, to engage a corresponding coupling feature of a light fixture.
