  • Medical wheelchair whose seat having a height adjustable function
    Patent number: 7931288
    Abstract: A medical wheelchair includes a support frame, a front bracket pivotally connected with the support frame, a rear bracket pivotally connected with the support frame, a mounting bracket pivotally connected between the front bracket and the rear bracket, a seat unit mounted on the mounting bracket, and a drive mechanism mounted between the support frame and the mounting bracket to move the mounting bracket and to adjust the height of the seat unit. Thus, the support frame, the mounting bracket, the front bracket and the rear bracket form a parallelogram linkage, so that the mounting bracket is moved smoothly to prevent the seat unit from being vibrated during adjustment of the height of the seat unit. In addition, the drive mechanism provides a buffering effect to the mounting bracket so that the mounting bracket and the seat unit are moved smoothly and stably.

  • Castor that is braked solidly and stably without producing vibration
    Patent number: 7930802
    Abstract: A castor includes an upright support post, a brake ring secured on the support post, a castor body rotatably mounted on the support post, two rollers rotatably mounted on the castor body, a first locking member movably mounted on the castor body, a second locking member movably mounted on the castor body, and a brake handle pivotally mounted on the castor body. Thus, when the castor is locked, each of the two rollers is locked onto and cannot be rotated relative to the castor body, and the castor body is locked onto and cannot be rotated relative to the support post, so that the castor will stop rotating when being braked so as to provide a double-braking effect.

  • Screwdriver with ratchet mechanism
    Patent number: 7926391
    Abstract: A screwdriver includes a first body having an end for coupling with a handle, a second body rotatably coupled to the other end of the first body, two pairs of engaging members, and a switch member pivotably mounted to the first body. Each pair of engaging members is slidably received in an associated transverse receiving section that includes two end openings in an outer circumference of the first body. Each engaging member includes a first end with an engaging portion. An elastic element is mounted between second ends of each pair of engaging members for biasing the pair of engaging members away from each other. The switch member is pivotable to selectively engage at least one of the engaging portions of each pair of engaging members with teeth of the second body, thereby controlling relative rotation between the first body and the second body.

  • Method for controlling brightness and increasing uniformity of light generated by lambertian surface sources
    Patent number: 7926969
    Abstract: A method for controlling the brightness and increasing uniformity of light generated by Lambertian surface sources has the steps of providing multiple pairs of Lambertian surface sources to produce light emitting on a target surface, each pair of Lambertian surface sources consisting of two Lambertian surface sources; rotating the two Lambertian surface sources of the same pair by a same rotation angle relative to the target surface but in opposite directions; calculating a maximum illumination and a minimum illumination corresponding to the rotation angle; determining whether a ratio of the maximum illumination to the minimum illumination is lower than a threshold; and fixing the Lambertian surface sources at the rotation angle if the ratio is lower than the threshold.

  • Methods and apparatus for handling products
    Patent number: 7921982
    Abstract: Apparatus (10) loads product in the form of bags into a carton held at a tilt angle. The leading ends of the bags on an adjustment conveyor (20) are abutted by a bumper (30) to reorient the bags 90° on the adjustment conveyor (20). The downstream roller (44) of a twist conveyor (40) is tilted to collate bags on a decline conveyor (70). The collated bags are moved on an orientation conveyor (74) to engage a product scoop (110) extending at an inclined position and moved to a vertical position to vertically orient the bags. The orientation conveyor (74) is moved to an offset position to allow the bags to drop onto a lowerator (92) of an accumulator (86) where they can be sandwiched between retainer plates (88, 90). A pusher plate (94) pushes the bags off the lowerator (92) into the carton and is tilted to correspond to the tilt angle of the carton.
