Abstract: A lighting device or system is configured to control of one or more parameters of light output, such as ON/OFF status, intensity when ON, color characteristics and position or orientation of light output (e.g. via a motorized luminaire control). The device or system may have other output capability, e.g. display projection or audio. Sensors or other input devices are responsive to the user. Responsive to user input, sensed activity, and/or acquired information, the device or system, controls a light source in accordance with a lighting control function. Operation of the light source and the lighting control function may be modified based on learning by the device or system.

Abstract: A shock absorber, for use with headgear having a faceguard, has a sliding member that does not extend beyond the support structure of the shock absorber in a way that would leave it vulnerable to damage. A headgear having a faceguard provides a protected mounting location for mounting a shock absorber for the faceguard.

Abstract: An enclosure is provided for use with a circuit protection system having at least one exhaust duct configured to route exhaust gases out of the circuit protection system. The enclosure includes a first barrier coupled to the circuit protection system, a second barrier coupled to the circuit protection system, and a top wall coupled to the first barrier and the second barrier. The first barrier and the second barrier define an exhaust plenum coupled in flow communication with the at least one exhaust duct. A vent extends through the top wall and is coupled in flow communication with the exhaust plenum to route the exhaust gases out of the enclosure.

Abstract: During implant of an implantable medical device, implanted cables or leads are inserted to a connector block. An insertion indicator provides the user with a visual indication the cables or leads have been correctly inserted into the connector block, which enables the implanted medical device to properly deliver treatment or receive signals via the implanted cables or leads. The insertion indicator may be provided by a mechanical indicator optically viewable once the lead has been correctly inserted, and/or may be provided by an electrically activated light indicator illuminated by a power source associated with the connector block or with a connector tool used to connect the lead or cable to the connector block upon correct insertion of the lead or cable. The insertion indicator may be permanently or removably disposed on the connector block, a connector tool, and/or a can associated with the connector block.

Abstract: An electrical connection apparatus includes an electrical connection contact and an adjustment component within an interior of the electrical connection apparatus. The electrical connection contact is operatively coupled to the adjustment component so that the electrical connection contact adjusts between an insertion position and a contact position in response to rotating the adjustment component. A slider movably arranged within the interior of the electrical connection apparatus causes the electrical connection contact to move in response to rotation of the adjustment component. The electrical connection apparatus includes one or more blocks, and the adjustment component, electrical contact and slider are arranged within an interior of the one or more blocks.

Abstract: Multiple seals, internal to a connector block, provide for connecting an implantable medical device and an implanted cable or lead. The forces to engage sealing or releasing the seals are derived from a mechanism so they can be relaxed to permit ease of insertion or withdrawal of a lead, or can be increased to tightly seal against fluid migration, and to provide an electrical insulation between adjacent conductors of the lead and connector block. During implant of the medical device, the lead is inserted and a shaft is rotated with a tool to engage the seals. Later, the seals can be released by rotating the control shaft in the opposite direction to allow extraction of the lead from the connector block. The seals therefore are able to provide improved sealing without increasing the insertion or the extraction forces for the lead.
