An elongate tubular lighting assembly having a body with a length between spaced first and second ends. The tubular lighting assembly has a source of illumination and first and second connectors respectively at the first and second body ends. The first connector has cooperating first and second parts having first and second surfaces. The first and second connector parts are configured so that the first and second surfaces are placed in confronting relationship to prevent separation of the first and second connector parts with the body in an operative state as an incident of the first connector part moving relative to the second connector part from a position fully separated from the second connector part in a substantially straight path that is transverse to the length of the body into an engaged position.

A control method of a robot cleaner for traveling to clean includes checking information about a predetermined traveling pattern; determining a traveling trajectory based on a traveling speed; generating a traveling pattern based on the determined traveling trajectory and the information about the predetermined traveling pattern, wherein the traveling pattern includes a first straight path, a first rotation path connected to the first straight path and for rotation in a first direction, a second straight path connected to the first rotation path, and a second rotation path connected to the second straight path and for rotation in a second direction; and repeatedly traveling along the generated traveling pattern at regular intervals. Therefore, since the robot cleaner performs cleaning without scattering dust, the efficiency of cleaning may be improved.

The inventive ablation element comprises an elongated cannula having a proximal end and a distal end. The cannula defines an internal lumen within the cannula and a cannula axis. A plurality of conductors contained within the lumen, each of the conductors has a proximal end proximate the proximal end of the cannula, and a distal end proximate the distal end of the cannula. A plurality of ablation stylets each has a proximal end and a distal end, and each coupled at the respective proximal end of the stylet to the distal end of a respective conductor, the stylets comprise a deflectable material, the conductors together with their respective stylets being mounted for axial movement. A trocar point defined proximate the distal end of the cannula. A deflection surface positioned between the trocar point and the proximal end of the cannula, the deflection surface being configured and positioned to deflect, in response to axial movement of the stylets in a direction from the proximate end of the cannula to the distal end of the cannula, at least some of the stylets laterally with respect to the cannula axis in different directions along substantially straight paths, the paths defining an ablation volume.

A driving assist apparatus for a vehicle that guides the vehicle to a target position is provided. On the basis of the present direction of the vehicle and the direction of the vehicle at the target position, a basic path that changes the vehicle direction so as to coincide with the target direction of the vehicle at the target position is computed. A path from the present position to the target position is computed by adding a straight-line path to the basic path under a predetermined condition.

Driving assist apparatus and method for a vehicle capable of accurately guiding the vehicle to a target region even if the initial state of the vehicle is a steered state are provided. On the basis of the present direction of the vehicle and the direction of the vehicle at a target position, a basic path P0 that changes the vehicle direction so as to coincide with the target direction of the vehicle at the target position is computed. A path P1 from the present position to the target position is computed by adding a straight-line path to the basic path under a predetermined condition.

An automatic screw feeding apparatus includes a base assembly, a slide assembly, a first spring, a screw carrier driving device, and a screw carrier guidance device. The slide assembly is mounted to the base assembly, movable forward and backward between a first position and a second position along a straight path. The first spring is mounted between the base and slide assemblies for keeping the slide assembly at the first position. The screw carrier guidance device includes a connection member connected with the base assembly, a guide member mounted to the connection member and movable forward and backward between a third position and a fourth position, and a second spring mounted between the guide and connection members for keeping the guide member located at the third position. The second spring can greatly lighten the load of the first spring to prevent the fed screws from being jammed.

An applicator device for a fluid, gel-like, pasty or powder product comprising a storage compartment in which the product is accommodated in free form, and an outlet for the product. A barrier is provided which in at least one operating condition at least partially blocks a straight path for the product from the storage compartment to the outlet.

The present invention is a compact fruit-vine harvester and separation system in which the harvested fruit travels along a vertical plane inside the harvester during processing, followed by a single turn for output. The system includes a machine and related methods for harvesting vine-borne crops. The machine provides for vine borne crops to be severed, separated, cleaned and machine-sorted along a straight path before making a single turn prior to exit. The machine incorporates a blower and / or suction system for efficient removal of unwanted dirt, vegetation and debris, and an optional roller to prevent clogging of the suction system.

An apparatus for sampling ambient air to obtain coarse and fine fractions of particulate matter includes a single acceleration tube and a collection tube coaxially arranged along a central axis with a gap between facing distal ends thereof within a range of d / D1 of 1 to 2, wherein d is the distance or gap between the distal ends and D1 is the inside diameter of the outlet at the distal end of the acceleration tube. A housing surrounding the acceleration and concentration tubes is provided with a side-wall nozzle connected to a suction device for drawing a major portion of the sampled ambient air therethrough and for separation of particulate matter, as a fine fraction, from that major portion. A second suction device draws a minor portion of the sampled ambient air, containing the coarse fraction of the particulate matter, in a straight path approximating the central axis, through the acceleration tube and through the collection tube for passage through a filter for separation of the coarse fraction of particulate matter. The ratio of the flow rates of the major and minor portions of the sampled ambient air is adjusted to provide a cutpoint within the range of 2-3 microns. The apparatus is preferably operated with a flow rate for the sampled ambient air within the range of 900-1200 liters per minute.

A method for accurately controlling the directional and turning movement of a self-propelled robotic pool cleaner while cleaning a pool includes the steps of propelling the pool cleaner in a first direction along a generally straight path from a first sidewall toward an opposing sidewall of the pool, wherein said pool cleaner is propelled to a position in the pool corresponding to a distance greater than the midpoint between the first sidewall and the opposing sidewall and before contacting the opposing sidewall of the pool; stopping the pool cleaner at the position and pivoting the pool cleaner to a predetermined angular change in direction; and reversing direction and resuming propulsion of the pool cleaner, wherein the pool cleaner moves in a second direction along a generally straight path that is angularly displaced from the first direction.
