Abstract: A camera retained in a waterproof underwater housing is controlled remotely and conveniently by a diver holding a hand-held remote device. The device can be a removable handle on the underwater housing, communicating with the camera, usually a movie camera, by infrared or other wireless protocol. Key functional camera settings, which would normally require navigation through a menu tree with a series of steps and selections, are selected by a single press of a button on the hand-held device. An important example is white balance calibration, which typically must be reset for every five feet of depth change.

Abstract: An LED underwater light, which can be hand-held or mounted on an underwater camera housing, is switchable between two light modes. A first embodiment of the dive light is a focus light, used for initial focusing with a still underwater camera. Incorporated in the focus light is a red light source to which the focus light can be switched from initially projected white light. The switch is used to switch off a series of white LEDs while switching on a series of red LEDs. In a second embodiment, the dive light is a flood/spot light, and enables a diver to quickly switch between flood and spot beams, via separate LED arrays.

Abstract: An underwater diving light has a rotatable front filter ring for selecting light filtration as needed for underwater still or video photography conditions. The filter ring is removable and interchangeable with different rings. Another important feature is efficient cooling of the LEDs and other internal electronics of the diving light assembly. The water is in contact with a metallic front face that conducts heat directly away from a metal core circuit board carrying the LED array or arrays. In one form of the diving light water channels are provided so that the ambient water can enter the assembly to spaces behind the LCD circuit board to efficiently cool the LEDs and associated electronics. The front plate assembly can be removable, for rinsing the internal cooling cavities, for interchange with different front face assemblies, and for air travel when the LCDs must be removed from driving electronics for safety concerns.

Abstract: An expandable tubular includes a plurality of leaves formed from sheet material that have curved surfaces. The leaves extend around a portion or fully around the diameter of the tubular structure. Some of the adjacent leaves of the tubular are coupled together. The tubular is compressed to a smaller diameter so that it can be inserted through previously deployed tubular assemblies. Once the tubular is properly positioned, it is deployed and coupled or not coupled to a previously deployed tubular assembly. The tubular is useful for all types of wells and boreholes.

Abstract: A bicycle tail light has a casing containing LEDs and a battery, as well as a universal mounting for engaging a bicycle luggage rack, a chain stay, a seat post or a rider's messenger bag, backpack or clothing. A swivel mounting is included for adjusting the light to an appropriate tilt angle, depending on the position of the bicycle component on which the light's base is mounted. The tail light projects light from both sides as well as to the rear, providing over 180° of visibility. A micro USB charging port for the battery is located at the outside of the light casing.

Abstract: A bicycle light system has front and rear (white and red) lights with mounting brackets to secure on a bicycle helmet. A battery is contained in the rear light casing, with an electrical cord extending between the front and rear light casings. The front light casing has controls for both front and rear lights, which can include different power levels and preferably a flash mode for the front light. The rear light can be separately controllable with a switch on the rear casing. 360° visibility preferably is provided via the front light, which projects colored light, such as amber, toward the sides. Helmet mountings for the front and rear light casings have a quick-release feature enabling the lights to be easily and quickly removed from the helmet, such as for recharging. For marine use appropriate light colors can be provided.

Abstract: A portable light apparatus includes a light housing with a light source and a separate battery case connected to the light housing with a cable. The light apparatus can be configured and used in several different ways: as a miner light or flashlight, with the light housing secured to an end of the battery case via a snap-in connection; as a bicycle light, with the battery case secured to a handlebar stem and the light housing secured to the handlebar or stem; a helmet light, with the battery case attached at the back of the helmet and the light housing at front; and as a headstrap light, with the light housing attached to the headstrap at a front position and the battery casing at a different position, preferably at rear. Clips, brackets and straps are included for adapting the light and battery case to the various purposes, without tools. Preferably the light housing is capable of pivoting on a base, so the user can adjust aim of the light beam.

Abstract: A bicycle light system has front and rear (white and red) lights with mounting brackets to secure on a bicycle helmet. A rechargeable battery is contained in the rear light casing, with an electrical cord extending between the front and rear light casings. The front light casing has controls for both front and rear lights, which can include different power levels and preferably a flash mode for the front light. 360° visibility preferably is provided via the front light, which projects colored light, such as amber, toward the sides. In a preferred embodiment the battery is rechargeable using a micro USB connection, a serial bus configuration widely used for cell phones, so that the battery will ordinarily be rechargeable via a cell phone recharging cable or a connection to a computer. Helmet mountings for the front and rear light casings have a quick-release feature enabling the lights to be easily and quickly removed from the helmet, such as for recharging.
