Abstract: A headlamp includes a strap configured to conform to a user's head or to a hardhat, and a first light assembly coupled to the strap. The first light assembly includes a flexible housing and a plurality of first LEDs operable in a first plurality of lighting modes. The headlamp also includes a second light assembly coupled to the strap and spaced apart from the first light assembly. The second light assembly includes a housing, a plurality of second LEDs, and a battery receptacle configured to receive a battery pack. The headlamp further includes an actuator operable to control operation of the first light assembly and the second light assembly, and a wire extending from the second light assembly to the first light assembly to electrically couple the battery receptacle to the plurality of first LEDs.

Abstract: A device may include a work light configured to emit light in a first direction. A device may include a hazard light configured to emit light in a second direction. A device may include a hinge coupled between the work light and the hazard light such that the work light and the hazard light are independently rotatable relative to each other about the hinge from a storage position to a deployed position. A device may include a user interface disposed on the hazard light, the user interface including a work light actuator engageable to actuate the work light and a hazard light actuator engageable independent from the work light actuator to actuate the hazard light.

Abstract: An improvement to anchor bolts adapted to be screwed into a patient's skull for the purpose of placing a depth electrode at a desired location within the patient's cranium. The improved anchor bolt includes an engineered controlled break point and recovery means such as a secondary fitting to facilitate removal if the anchor bolt is impacted and breaks or bends at the controlled break point. The anchor bolt is intended to be used in a similar manner to existing anchor bolts with the added benefits of protecting the patient from excessive harm from violent impact of anchor bolts which can occur during seizures for example, as well as facilitating removal of remaining parts of a damaged anchor bolt without the need for surgical intervention and in a relatively easy fashion.

Abstract: A launching system for an air gun includes a compression cylinder. The compression cylinder includes a cylinder body having an open rearward end and a closed forward end with an interior bore therebetween. The forward end has a transfer port configured for fluid communication with a barrel of an air gun. The piston includes a piston body. The piston body has a forward portion disposed within the interior bore. A sealing device is disposed on the forward portion of the piston body. One of a ferromagnetic section or magnet is disposed on a rearward portion of the piston body. A drive coil assembly is disposed over the one of a ferromagnetic section or magnet. When the drive coil assembly is energized with a first polarity, the piston is drawn from a reset position to a firing position relative to the compression cylinder by the drive coil assembly with increasing force.

Abstract: A loading mechanism includes a housing including a loading chamber positioned adjacent to a housing passageway. The loading chamber is operable to load ammunition therein. A resilient bucking is disposed within the housing passageway. The bucking includes a bucking passageway that is operable to receive ammunition transferred from the loading chamber. A spring, having a plurality of spring coils, is disposed in the housing passageway. The spring is operable to apply pressure to the bucking when the spring is compressed. A gun barrel is slidably positioned within the housing passageway. A fastening mechanism is operable to attach the gun barrel to the housing and to put the spring into compression. When the spring is compressed, pressure is applied to the bucking and the bucking passageway is collapsed inward to seal entirely around ammunition that is positioned within the bucking passageway.

Abstract: A portable lighting apparatus includes a handle, a light head pivotally coupled to the handle through a plurality of positions via a joint, a battery receptacle supported by the handle, a first light source supported in the light head, a second light source supported in the light head, and a user interface supported by the handle and configured to be selectively actuated by a user to operate the first light source and the second light source. The battery receptacle is configured to receive a rechargeable battery. The first light source includes a laser selectively operable to emit a single light wavelength, and the second light source includes one or more LEDs selectively operable to emit a distribution of light wavelengths.

Abstract: In an apparatus for measuring the eccentricity of an eccentric bearing face having an axis of rotation, a rotary motion and a perimeter, the apparatus comprises a length measurement gauge, mounting means for mounting the length measurement gauge, means for guiding the movement of the length measurement gauge, in which the guiding means comprises a follower and two bearing tips, and means for applying the bearing tips to the eccentric bearing face. The mounting means for mounting the length measurement gauge functions to (a) maintain the length measurement gauge in the radical direction during rotary motion, and (b) enable the length measurement gauge to move perpendicularly to the axis of rotation. The guiding means functions to guide the movement of the length measurement gauge in the direction of the rotary motion of the eccentric bearing face.
