The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A digital-pointer interaction system is provided, which includes a display apparatus, a host, a wireless receiving device, and a plurality of wireless pointer devices. The host plays a display screen on the display apparatus, and executes a digital-pointer application. The digital-pointer application renders a plurality of pointer cursors on the display screen according to a number of wireless pointer devices connected to the wireless receiving device, and each wireless pointer device corresponds to each pointer cursor. Each wireless pointer device periodically emits an indication signal to the wireless receiving device, and the wireless receiving device transmits the indication signal to the host. The indication signal includes displacement information of each wireless pointer device. The digital-pointer application controls movement of each pointer cursor on the display screen according to the displacement information of each wireless pointer device.

Abstract: A luggage handle includes a support unit, a control unit and an operation unit. The support unit includes an outer tube having at least one locking hole. The control unit includes a first casing, a second casing, a slide, a push spring, a push shank, an elastic member, a weight and a restoring spring. Thus, when the luggage handle is subjected to a larger shock, the weight is moved downward to move its stop block to abut the limit block of the slide to prevent the locking stub of the slide from being detached from the locking hole of the outer tube and to prevent the pull bar and the inner tube of the operation unit from being moved outwardly from the support seat of the support unit.

Abstract: An anchoring apparatus includes an upper anchoring assembly located at a lower end of the inner tube of a pulling bar assembly and a lower anchoring assembly located at a lower end of the middle tube of the pulling bar assembly. The lower anchoring assembly has a lower engaging seat which has a coupling bore and an aperture formed on the side walls for housing a lower extensible button. When the bottom end of the upper anchoring assembly is located above the top end of the lower anchoring assembly, a jutting stub of the lower extensible button may be urged to retract and an anchor bolt may be extended to engage with the anchor bore of the outer tube of the pulling bar assembly to thereby keep the pulling bar in a steady and secured condition.

Abstract: An extensible anchoring apparatus for a multi-section pulling bar of a trunk has an anchoring means located in a pulling bar means to allow the pulling bar positioned securely at the retracted condition. The pulling bar means includes a handle having two ends each has a bottom side fastened to an inner tube with a linkage bar located therein. The inner tube is housed in a middle tube and the middle tube is housed in an outer tube. The tubes have respectively latch bores formed on the tubular walls. The outer tube further has an anchor bore located at the bottom section. The anchoring apparatus comprises an upper anchoring means located at a lower end of the inner tube and a lower anchoring means located at a lower end of the middle tube. The lower anchoring means has a lower engaging seat which has a coupling bore and an aperture formed on the side walls for housing a lower extensible button.

Abstract: A combination of a retractable handle device and a suitcase includes a first base member and a second base member connected to the back of the suitcase, each of the two base member having a slot defined therein. The handle device includes a base portion with two wheels and two outer tubes extend from the base portion. Two first inner tubes are retractable received in the two outer tubes and two second inner tubes are retractably received in the first inner tubes with a handle fixedly connected to the two second inner tubes. Two engaging members are respectively and slidably connected between the two first inner tubes the two second inner tubes. The base portion is disengagably engaged with the second base member. Each of the two engaging members has a connecting member disengagably connected thereto which is engagable to the base member corresponding thereto.

Abstract: An improved pull rod structure for use on a trunk is equipped with a pair of retaining posts each having a plurality of closely defined locking recesses. The retaining post is housed in an integrally formed side groove of an outer sleeve in which an inner tube having a latch assembly disposed in a tubular housing is secured to the bottom end. A spring biased latch fixed to the bottom end of a vertical driving linkage rod can be actuated to stick out of or retrieve a protrusion from an opening to selectively engage one of the locking recesses in a nearly stageless manner when a pivotal control member engaged with a handle of a trunk is pivoted or released.

Abstract: A controlling handle structure for pull rods of a luggage, including a handle member having a receptacle, a lower base received in the receptacle of the handle member and having a chamber and a controlling mechanism received in the chamber of the lower base. The controlling mechanism includes a first linking arm which is connected with a press button at one end and has an engaging section at the other end, and a second linking arm having an engaging section opposite to and engaged with the engaging section of the first linking arm, wherein the press button is depressably received in the through hole of the handle member to pivotally drive the first linking arm which reversely pivotally drives the second linking arm, whereby locking members disposed below the first and second linking arms are simultaneously moved to lock the pull rods.

Abstract: A pull rod structure of a baggage cart, comprising a handle body, a controlling mechanism, a lower cover, a transmission mechanism, a linking mechanism, two hollow tube members and two sleeve members. The handle body is formed with two through holes at two ends and two insert holes formed beside the through holes. A locking channel is formed under the insert hole for receiving a locking block. A pull lever is disposed on one side of the handle body, having two ends inserted in the insert holes thereof to couple with the locking block. The locking block receives a spring and the pull lever. A long pin fixedly connects the pull lever with the locking block and a short pin is inserted into a pin hole of the locking block, a pin hole of the pull lever and the spring so as to fix the pull lever with the locking block. The long pin partially protrudes outside the locking block to press a pressing lever of the transmission mechanism.

Abstract: An improved pull handle for use on a trunk is provided with an inverted U shaped grasp handle which is engaged with a hollow rod at each end thereof. Each hollow rod is inserted into a positioning tube. One of the positioning tubes is provided with a plurality of spaced slots thereon. An elongated rod having a press button associated with the top thereof is inserted into one of the hollow rods and a cam member is secured to the bottom end of the spring biased actuation rod. The cam member housed in a sleeve member having a slot disposed at the bottom thereof is in abutment against a spring biased base seat which is provided with a tilted surface in correspondence to the cam member. The base seat is supported in place by a round plate in the sleeve member. An extension tongue is disposed on the base seat and can stick out of or retract from the slot of the sleeve member and also the slots of the positioning tube when actuated by the cam member to slide outwardly or inwardly in the sleeve member.
