Abstract: A surgical device controlled by a control console includes a device body, an identification circuit in connection with the device body, and a communication interface. The communication interface is configured to communicatively connect the identification circuit to the control console. In response to receiving an energization signal from the control console via the communication interface, the identification circuit activates an identification signal at a fixed frequency for a predetermined period of time and communicates the identification signal to the control console via the communication interface.

In at least one embodiment, the medical device system may be configured to dynamically switch motor control protocols while the motor is operating based on input from one or more sensors configured to monitor a motor, including, but not limited to, monitoring a magnetic flux field of the motor or monitoring current to the motor. The medical device system may dynamically switch motor control protocols between motor control protocols, including, but not limited to, Six-Step Commutation, Hall-Based Sinusoidal Commutation and Field Oriented Commutation.

Abstract: An adaptive flow rate control system for a surgical device, whereby the control system includes one or more nonintrusive sensors configured to be positioned on an aspiration conduit extending downstream from a handheld surgical device to measure flow and reduce clogging within the aspiration conduit is disclosed. The nonintrusive sensor may provide data to a controller of a handheld surgical device system to enable it to control operation of the handheld surgical device based at least in part on the data from the adaptive flow rate control system to prevent clogging of the aspiration system. The adaptive flow rate control system may also include a clog tracking module and a clog prediction module. The adaptive flow rate control system may include a wireless communication system configured to communicate with other components of a surgical device system and may communicate with a external network and resources on the internet.

Abstract: A medical device system configured to dynamically control a shaver window opening via controlling positioning of an opening in an inner drive shaft relative to an opening in an outer housing based on continuously tracking the motor is disclosed. The medical device system may include a shaver at a distal end and an aspiration system configured to aspirate material through the inner drive shaft. A processor of the medical device system may control rotational motion of the inner drive shaft based on continuously sensing the position of the opening in the inner drive shaft to reduce clogs and increase cutting effectiveness of the system. By continuously monitoring the medical device system, the processor can correct out of phase conditions in oscillation mode to prevent poor cutting conditions. The processor can also dynamically determine a reversal position on the opening in the inner drive shaft to create a desired cutting action.

Abstract: An outdoor overhead lamp assembly uses light emitting diodes to provide illumination for an area to be illuminated. The lamp assembly includes a unitary housing, which may be formed from a single casting. The housing includes mechanical mounting structure for mounting the housing to a mast arm. The housing includes an electrical compartment for housing electrical components and connections. Heat sink fins are formed on the integral housing that provide for thermal control of the electronic components and LED modules within the lamp assembly. The LED modules are mounted to aiming platforms within an optical compartment for the assembly. An external lens provides environmental protection for the LEDs and their individual lenses. The housing may also include structures for mounting decorative coverings or “skins” to accommodate different aesthetic requirements.

Abstract: A light unit that includes an internal power supply that may be used in the event of an external power failure to provide power to the light unit. In one aspect, the present disclosure provides a lighting apparatus, comprising (a) a power input configured to receive external power from an external power source; (b) a solid state light element that is interconnected to the power input; (c) a detection circuit interconnected to the power input and that, when power is not provided to the power input, measures input impedance at the power input and determines if there is a lack of external power; and (d) a back-up power source that is interconnected to the solid state light element and the power input and that provides power to the solid state light element when the light element is; not provided with power from the power input.

Abstract: An adapter plate is provided that fits an existing luminaire in place of an existing globe that mounts to the luminaire. A heat sink mates to the adapter plate and also houses a solid state light engine and associated electronics. The heat sink may provide an enclosed, protective volume for the associated electronics, such as a power supply for the solid state light engine. A globe mounting ring attached to the heat sink allows either an existing globe to be re-mounted or a new globe to be installed.

Abstract: A lamp assembly manages thermal energy output from solid state lighting elements. An aspect of the present disclosure provides a lamp assembly that achieves enhanced cooling of light elements within the assembly. Enhanced cooling is achieved, in this aspect, by providing a lamp assembly including a heat sink having a plurality of thermo bosses protruding therefrom on a first side, and a plurality of heat sink fins on a second side. A printed circuit board is secured to the first side of the heat sink, and has a plurality of through holes that correspond to the size and locations of the thermo bosses, such that when the printed circuit board is secured to the heat sink, the thermo bosses extend into the through holes.

Abstract: A luminaire for re-use, a retro-fit device, or mechanism, that are designed to both fit into an existing luminaire while also making efficient use of LEDs or other solid state light elements is provided. Thermal elements are provided that act to remove heat generated by light elements. A housing is provided that may be configured to receive LEDs, or other optical elements, that are aimed to provide light in a desired direction through mounting to a facet or mounting surface, and have effective thermal environment control through one or more fins mounted to the side of the facet opposite the light element. Luminaires are provided for both original designs that utilize solid state light elements, and retrofit assemblies designed to convert an existing luminaire (that uses a traditional light source or sources) into a luminaire that uses solid state light elements.

Abstract: Light assemblies are disclosed which incorporate mechanisms by which light losses due to angle of incidence from a lens covering an LED, or other solid state source or sources, are reduced. Assemblies may incorporate low-loss covers in luminaires originally designed to utilize LEDs or in an LED retrofit device or mechanism designed to convert an existing luminaire that uses a traditional light source or sources into a luminaire that uses LEDs. The low loss covers include discrete surfaces that correspond to individual LEDs, small arrays of LEDs, or small groups of LEDs. The discrete surfaces may be substantially orthogonal to the rays of light that are incident upon the surfaces from the associated LED(s) to reduce the amount of light reflected back to the associated LED(s).
