Abstract: Apparatus for loading into an injection device and comprising a syringe and a boot remover. The syringe has a syringe body, a needle and a boot providing a sterile cover for the needle. The boot remover has a body for substantially enclosing the boot and a lip or lips projecting inwardly to engage a junction between the boot and the syringe body. The boot remover also has, at its widest point, substantially the same outer dimension as, or a smaller outer dimension than, the syringe body. The apparatus can be loaded into an injection device through an opening at a distal end of the device such that, when loaded, a portion of the boot remover projects through a proximal end of the device to facilitate removal of the boot remover and boot by a user. This arrangement allows a user to remove the boot from the syringe by holding and pulling on said grip.

Abstract: A protection circuit for an HID dimming circuit is provided. A resistive component limits the initial current after a relay closes and current flows from a charged capacitor to a second capacitor. An inductive component limits the rate of change of current through the circuit. A voltage limited device limits voltage across the contacts of a solid state relay. The circuit is preferably formed in a small module that is adapted to be plugged into an HID lighting device.

Abstract: Apparatus for removing a needle assembly from an injecting device, the needle assembly comprising a needle holder portion and a needle portion secured to, or integral with, the needle holder portion, the needle assembly being attachable to the injecting device via the needle holder portion, the apparatus comprising a housing (2) having an opening (5, 10, 12) through which the needle assembly can enter the interior of the housing, wherein within the housing there is provided a receiving portion (20) which is arranged to receive the needle holder portion in such a way as to impede rotation of the needle holder portion with respect to the receiving portion, and wherein the opening is formed such that the needle portion can enter the housing and the needle holder portion can enter the receiving portion by means of a relative movement between the housing and the needle portion which relative movement is lateral with respect to the axis of the needle portion.

Abstract: An interface apparatus for interfacing an AC power source, a control panel and a luminaire. The interface apparatus includes a input/output port that is adapted to receive a communication signal from the control panel and transmit the communication signal to the luminaire and to a second interface apparatus; and a power cord adapter, that is adapted to receive an AC power signal from the power source and provide the AC power signal to the luminaire and to the second interface apparatus. In another embodiment of the present invention, a luminaire provides an input/output port that is adapted to receive a communication signal from a control panel via the input port and transmit the communication signal to another luminaire via the output port.

Abstract: A lamp ignition circuit is provided which can initiate operation of a gas discharge lamp using a driving voltage which is similar in magnitude to the lamp operating voltage. The lamp ignition circuit is useful with a semi-resonant ballast and lamp circuit in which switching operations intrinsic to the lamp shock-excite a series-connected inductor and capacitor into semi-resonant operation corresponding to an energy exchange and transfer during each half-cycle of the alternating current source to drive the lamp to start and maintain operation of the lamp using line voltage. The ignitor circuit has a disabling function following ignition of the lamp which is operable when the operating voltage of the lamp is approximately the line voltage of the power source. The disabling function triggered by an increase in voltage across the ignition circuit following operation of the lamp.

Abstract: An apparatus and method for controlling a plurality of lighting fixtures. A start controller provides power to the plurality of lighting fixtures. A control power timer connected to the start controller provides a first time period for illumination of the plurality of lighting fixtures, wherein the start controller is operable to interrupt power to the plurality of lighting fixtures when the first time period expires. A control timer connected to the control power timer provides a second time period for illumination of the plurality of lighting fixtures, wherein the second time period commences and then elapses before the end of the first time period. A control flasher connected to the control timer alternates the plurality of lighting fixtures between a high power state and a low power state during the second time period for illumination. An end user is alerted to the termination of the illumination of the plurality of lighting fixtures before termination occurs.

Abstract: An ignitor and ignitor monitoring device is provided which is externally and detachably mounted to a high intensity discharge (HID) luminaire. The ignitor monitoring device provides a visual indication of whether or not the ignitor of the lamp in the HID luminaire is functioning. If the lamp is not operating and the indicator is activated, sufficient open circuit voltage is present to operate the ignitor, the ballast in the luminaire is most likely functioning properly, and power is present to operate the luminaire. A service person can assume that the lamp is defective and can replace the lamp as a first attempt to correct the problem with the luminaire. If the lamp is off and the indicator is also not operating, the luminaire is not operating for any of a number of reasons such as a defective ignitor, a defective ballast capacitor, a defective lamp or loss of supply voltage from the power source. A service person can replace the ignitor in a first attempt to repair the luminaire.
