A ski attachment kit for a kick scooter having a scooter steering assembly that includes a front fork configured for attaching a front wheel, a scooter body that includes a stand-on area and a rear fork rearward of the stand-on area configured for attaching a rear wheel, and a coupling that couples the steering assembly and the scooter body. The kit includes a front ski assembly having a scooter steering assembly mount that receives and releasably retains the steering assembly while providing a clearance for an attached front wheel. The kit also includes a rear ski assembly having a scooter body mount that receives and releasably retains the scooter body while providing a clearance for an attached rear wheel.

An inbred corn line, designated W69079, is disclosed. The invention relates to the seeds of inbred corn line W69079, to the plants of inbred corn line W69079 and to methods for producing a corn plant, either inbred or hybrid, by crossing the inbred line W69079 with itself or another corn line. The invention further relates to methods for producing a corn plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other inbred corn lines derived from the inbred W69079.

A method, system and applicator for the solvent-less delivery of a bio-active material to a receiver. The applicator includes a discharge device, a reservoir which holds a bioactive material, and a solvent at a supercritical fluid state for delivering the bioactive material through the discharge device to the receiver. A spacer may be positioned between the discharge device and the receiver. The receiver may have a plurality of different bio-active material to be applied to a subject, each located at a different location on the receiver.

A demodulator, suitable for use in a communication system and in a modem, has a block polyphase circuit with circuit blocks for different signal processing functions, particularly filtering, delay, and frequency conversion. The circuit blocks are arranged for parallel processing of different portions of an input sequence of signals. Signals of the input sequence to be filtered are divided among the blocks by a demultiplexer for processing at a clock frequency lower than a clock frequency of the input signal sequence. Signals outputted by groups of the circuit blocks are summed to produce an output signal of the group. Frequency and timing reference signals, as well as fractional delay interpolation, are produced also by parallel-channel circuitry. Output signals of all of the groups are multiplexed to provide an output signal sequence such that the repetition frequency of the outputted signals may be higher, lower, or equal to that of the input signal sequence. This enables use of programmable circuitry operative at clock rates lower than rates required to process directly the input signal sequence.

A new kinetic spray process is disclosed that enables one to secure a plurality of ceramic elements together quickly without the need for glues or other adhesives. The process finds special utilization in the formation of non-thermal plasma reactors wherein the kinetic spray process can be used to simultaneously secure the ceramic elements together and to form electrical connections between like electrodes in the non-thermal plasma reactor.

Authentication systems, apparatus, and methods authenticate an identification marking including a nanocrystalline material. One or more properties of the marking are ascertained to provide a measured profile. The measured profile is compared to at least one member of a closed set of reference profiles. Each reference profile has predetermined values of one or more properties. Each reference profile is unique within the set. At least one reference profile is characteristic of an indicator material in a nanocrystalline morphology and non-characteristic of the same indicator material in a bulk morphology.

摘要:
A compact external fixation device for the treatment of bone fractures of reduced dimensions and of children comprises a pair of clamps (2, 3) for bone screws (V) connected by respective spherical joints (5, 6) and a central body (4) formed by at least one male element (7) and one female element (8) which are telescopically coupled. In a preferred embodiment, one element (7) is made of a material of high radiotransparency and the other element (8) is made of a substantially radiopaque rigid material with walls of such minimum thickness as to be at least partially radiotransparent. Antirotation means are provided between the male telescopic element (7) and the female telescopic element (8); transverse eccentric pins (34, 35) contained in each clamp act on respective slides (28, 29) for locking the ball (24, 25) of each joint. The fixation device permits complete radioscopy of the fracture even through the central body; the device is light in weight and of small dimensions, due to the provision of the means for locking the joints within the clamps.
