Abstract: A wheelchair includes a chair frame mechanism and two pedal mechanisms. The chair frame mechanism includes a frame body and two pedal-mounting rods. The pedal mechanisms are respectively mounted to the pedal-mounting rods. Each of the pedal mechanisms includes a pivot unit sleeved on the corresponding pedal-mounting rod and having has a guide groove, a positioning unit mounted to the corresponding pedal-mounting rod and engaging the guide groove, and a pedal unit mounted to the pivot unit.

Abstract: A CBR-based negotiation RBAC method for ubiquitous resources management is described. The method, which is applicable to serving servers, includes steps of inquiring for a similar case in a case base in order to obtain an initial case, performing a REUSE procedure or a REVISE negotiating procedure on the initial case to assign at least one appropriate role set consisting of a local role and a virtual role, performing a local role and virtual role fitting procedure to fit the local role and the virtual role, and performing a determining and retaining procedure to meet the requirements of users during the negotiation process.

Abstract: The present invention relates to a controlling apparatus for bending the tube of an endoscope, in which the tube of the endoscope is consisted of different rigid and soft parts. The tail portion of the tube is provided at least with a soft foldable ring and other rigid portion becomes a support base. A slot is formed in the tube for receiving a controlling slice, which has an elastic end being bent in tenseness and the other end extending into a handle to engage with a teeth piece. A gear set provided within the handle engages with the teeth piece. By turning the gear set, it can move the teeth piece as well as the controlling slice toward the tail portion of the tube to control the tail portion being bent under simple operation. When the controlling slice moves towards the handle and is apart from the soft foldable ring of the tube, the tail portion will be recovered flatly because of being lack of elastic force.

Abstract: The present invention is aimed to design an improved lighting assembly for camera module of an endoscope. The camera module is received in a cylinder body, which is connected with the tail end of the tube of the endoscope. The character of this invention is to provide a secondary lighting apparatus between the cylinder body and the tube. The secondary lighting apparatus includes several LEDs being mounted inside annular-arrayed and covered by a transparent ring. The annular-arrayed LEDs can emit light through the transparent ring with 360 degrees lighting outwards that provides a perfect lighting effect for capturing the inner images of patients and will facilitate the judgement of users or doctors.

Abstract: The present invention relates to an improved lighting assembly for camera module of an endoscope. The camera module is received in a cylinder body, which is connected with the tail end of a tube of the endoscope. The cylinder body is provided with two side openings covered by related transparent caps. Several lighting sources are mounted in the cylinder body at the position near the side openings that emits side lightings to increase whole lighting effect in the working cavity and facilitates to obtain clear image captured from camera module. Moreover, the front cover is provided with an annular misty portion related to the position above the front lighting sources around the camera module. Hence, the forward emitting lighting will be foggy that can thus avoid from the reflected lighting spots and benefit the use of the present endoscope to catch clear images of patient's inner cavity.

Abstract: The present invention relates to a portable medical platform system of an endoscope, which includes a camera head, a tube, a handle, and a portable main system. The camera head having light sources, a sensor, and an image signal processor is mounted in a distal end of the tube. The other proximal end of the tube is connected with the handle which has provided with several functional buttons thereon for electrically connecting with a control board to control actions of light sources and the camera head wherein the portable main system is also connected with the control board. By providing the control system on the handle with separated control board, the invention therefore obtains utility and improvement for a medical surgery.

Abstract: A digital swappable endoscope including pipe end and host end is provided. The pipe end includes lens module, image sensor, and sensor processor. The lens module is configured to capture a light. The sensor processor is connected to the image sensor and transforms the light into a digital sign. The host end includes a programmable logic device and a CPU. The programmable logic device is connected to the pipe end and configured to receive the digital signal. The CPU is connected to the programmable logic device. The programmable logic device is configured to determine the signal format of the digital signal. The programmable logic device carries out the following step after determining: A. if the signal format is conformed to specification, the digital signal is transmitted to the CPU; and B. if the signal format is not conformed to specification, a simulation signal is transmitted to the CPU.
