An artificial functional spinal unit including an expandable intervertebral implant that can be inserted via a posterior surgical approach and used with one or more facet replacement devices to provide an anatomically correct range of motion is described. Lordotic and non-lordotic expandable, articulating implants and cages are described, along with embodiments of facet replacement devices and instruments for insertion. Methods of insertion are also described.

A light bulb includes a bulb body, a light guide, and at least one light-emitting diode (LED). The bulb body includes a light-transmitting shell and a conductive base. The light-transmitting shell is mounted to the base. A circuit board is fixed at one side of the base and is in electrical connection with the base. The LED is mounted to the circuit board that is arranged at one side of the base, and the LED is in electrical connection with the circuit board to provide an internal light source. The light guide is arranged inside the bulb body and has an end forming a cavity that receives the LED therein, whereby the light guide is set erect on the base. As such, advantages of easy manufacturing, reduced costs, operation safety, increased angular range of illumination, and extended lifespan can be provided.

Embodiments of the invention are concerned with a radar system, and relates specifically to scanning radar systems that are suitable for detecting and monitoring ground-based targets.In one aspect, the radar system is embodied as a scanning radar system comprising a frequency generator, a frequency scanning antenna, and a receiver arranged to process signals received from a target so as to identify a Doppler frequency associated with the target, wherein the frequency generator is arranged to generate a plurality of sets of signals, each set having a different characteristic frequency, the frequency generator comprising a digital synthesiser arranged to modulate a continuous wave signal of a given characteristic frequency by a sequence of modulation of patterns whereby to generate a said set of signals, and wherein the frequency scanning antenna is arranged to cooperate with the frequency generator so as to transceive radiation over a region having an angular extent dependent on the said generated frequencies.Embodiments of the invention thus combine digital synthesiser techniques, which are capable of precise frequency generation and control, with passive frequency scanning and Doppler processing techniques. This enables accurate control of range and of scan rates, and enables optimisation of range cell size for factors such as slow and fast target detection and Signal to Noise ratio, and thus enables detection of targets located at distances considerably farther away than is possible with known systems having similar power requirements.

A structure of overhead lamp and mounting bracket for constructional vehicle has developed to tilt the illuminating angle by controlling the position of slits at the lateral sides of bracket. The lamp is securely fixing at the controlled position at one of 4 positions and the position controlling slits. The main case is securely fixed to the bracket by installing a connection screw and a hinge bolt for restricting unwanted rotation of the hinge bolt. Accordingly, since a position controlling rib having a position controlling slit is extended rearward from side supporters, the illumination angle can be controlled within a greater range. The main case can be supported at 4 points through the plurality of position controlling slits. Furthermore, by fitting the connection screw with an outer circumferential recess of a hinge bolt fastening lever, rotational separation of the hinge bolt and change of the illumination angle of the main case can be prevented.
