A walking-assistant device is provided comprising a driving unit that includes four wheels and four actuators for adjusting heights of the four wheels, a mechanism unit that includes two vertical frames whose length is adjusted and connection frames for fixing and connecting the vertical frames, and a manipulation unit that includes a plurality of sensors for grasping a user's moving intention and controls the driving unit and the mechanism unit based on a signal detected by the sensors.

The invention provides a chute system (C1,C2,C3) for a sorting system arranged for transporting objects, e.g. for use for discharging luggage from a conveyor system. The chute system has one or more chute sections with an inlet (IL) in one end and an outlet (OL) in the opposite end. Displacement means, e.g. a pneumatic actuator, is arranged to adjust an angle of inclination of the one or more chute sections (C1,C2,C3) by displacing the chute section (C1,C2,C3) in a motion comprising pivoting around a pivot point positioned downstream of the inlet (IL). E.G. the pivot point can be positioned at the outlet, e.g. by means of a hinge. The adjustment of the angle of inclination may be controlled by a processor in response to various position and / or speed sensors and / or information about incoming objects from a vision based system or from the associated sorting system, e.g. identification of poly wrapped objects. The angle of inclination can be increased in case an object stops on the chute section, or the angle of inclination can be decreased in case an object moves too fast, even if a simple gravity chute is used. A cascade of two or more chute sections (C1,C2,C3) with adjustable angles of inclination can be used to control batches of objects and to control back pressure of objects on the chute.

Apparatus (10) comprises a base (12), a plurality of posts (14) attached to the base (12), and a platform (16) defining a surface (18) for supporting at least one mail tray. The platform (16) is coupled to the four posts (14) and is moveable therealong between a first position (20) and a second position (22) (shown in phantom lines) below the first position (20) when a first object (e.g. a full tray) is supported on the surface (18) of the platform (16). As other full trays are stacked on the apparatus (10), the platform (16) is displaced further from the first position (20) until eventually it reaches the base (12). When the full trays are unloaded from the apparatus (10), the platform (16) rises upwards, returning to the first position (20) when none remain on the surface (18). As the platform (16) rises, a space (32) between the platform (16) and the base (12) opens up and is a convenient place to store empty trays.

A method of operating a laser to obtain an output pulse having a single wavelength, comprises inducing an intracavity loss into a laser resonator having an amount that prevents oscillation during a time that energy from the pump source is being stored in the gain medium. Gain is built up in the gain medium with energy from the pump source until formation of a single-frequency relaxation oscillation pulse in the resonator. Upon detection of the onset of the relaxation oscillation pulse, the intracavity loss is reduced, such as by Q-switching, so that the built-up gain stored in the gain medium is output from the resonator in the form of an output pulse at a single frequency. An electronically controllable output coupler is controlled to affect output pulse characteristics. The laser acts a master oscillator in a master oscillator power amplifier configuration. The laser is used for laser peening.

To securely position a needle tip and a blade face of a needle tube inserted into the skin in a predetermined site of a living body, such as the upper layer of skin, an injection needle assembly includes a needle tube having a needle tip capable of puncturing a living body, a hub holding the needle tube, a stabilizer, and a guide portion. The stabilizer is formed in a tubular shape surrounding the circumference of the needle tube, and an end face is pressed against the skin, and thereby a raised portion of the skin is formed in a tube hole. The guide portion is arranged on the stabilizer, and is adapted to recognize a press-in distance y of the stabilizer to the skin.
