Articulated artificial finger assembly
Disclosed is an articulated artificial finger assembly, which can be controlled by the remaining portion of an amputated finger. An adjacent finger is used to manipulate the device when no finger is present. When the stump or adjacent finger begins to bend at the first knuckle, the rest of the device will react to the movements and articulate in the natural manner of a human finger. There are two embodiments shown which, can accommodate a variety of cases. The first embodiment relates to an amputated finger with a portion of the finger remaining. The second is used when a total finger is absent. In either case, the first embodiment uses a ring that is placed over the remaining stub of the finger and the second embodiment a ring is placed over an adjacent finger. The ring, in either embodiment, actuates upper and or lower actuation drives, which are reciprocally and transversely attached to a pivoting block. The pivoting block is fastened to an adjustable middle phalangeal section. The transversely connected upper and lower actuation drives cause the middle phalangeal section to curl under when articulated. The middle phalangeal section is comprised of two main body parts. The first is an outer phalangeal section and the second phalangeal section is placed inside the outer phalangeal section and fastened thereto. A forward fingertip section is pivotally fastened to a forward end of the inner phalangeal section. A forward end of the upper actuating drive is pivotally connected to the forward fingertip section. A supple cover is placed over the device once it is assembled. An inner supple cover is inserted into the device and sealed along the edges of the outer supple cover. To complete the device a screw is inserted into the fingertip, passing through the supple cover and is then hidden by an artificial fingernail placed thereon.

A mechanical finger comprises at least two phalanges. The phalanges have tubular bodies made of a semi-rigid material. One phalange is adapted to be secured to a base. Another phalange is connected to an adjacent phalange for pivoting movement with respect to the adjacent phalange. A skeleton member in the tubular bodies of the phalanges moves to actuate the pivoting motion of the phalanges with respect to one another. The skeleton member is connected to a degree of actuation to cause the pivoting motion of the phalanges with respect to one another. An assembly is also provided. The assembly comprises at least two of the mechanical finger, a palm actuator comprising a base for connection of the base phalange of each mechanical finger, and at least one degree of actuation connected to the skeleton member. The degree of actuation causes a grasping movement of the mechanical fingers.

Pulse wave sensor device
Disclosed is a pulse wave sensor device with a light emitter (6) and a light receiver (7) provided on the surface of a peripheral wall section (2B) of a case (2). On the surface of the peripheral wall section (2B) of the case (2), a blood flow impedance reduction section (15) is provided on the right hand side of the light emitter (6) and the light receiver (7) and a fingertip positioning section (16) is provided to the left of the light emitter (6) and the light receiver (7). When a user brings the distal phalange (A) of a finger (F) into contact with the light emitter (6) and the light receiver (7), the middle phalange (B) of the finger (F) comes into contact with the contact section (15C) of the blood flow impedance reduction section (15). A difference in level arises between a section on the case (2) at the periphery of the light emitter (6) and light receiver (7) and the contact section (15C), reducing the pressure on the section of the distal phalange (A) of the finger (F) close to the first joint.

There is disclosed a prosthetic full finger assembly. In an embodiment, the assembly includes a distal phalanges. The assembly further includes a middle phalanges having an operable connection with the distal phalanges. The assembly includes a proximal phalanges ring having an operable connection with the middle phalanges. The assembly includes a proximal phalanges yoke having an operable connection with the proximal phalanges ring. The assembly includes a metacarpal back plate having an operable connection with the proximal phalanges yoke and an operable connection with the proximal phalanges ring. The assembly includes an anchoring portion having an operable connection with the metacarpal back plate at a location proximal of the operable connection of the proximal phalanges ring. Other embodiments are also disclosed.

A robot hand equipped with a function of gently pinching an object to be held is provided. A single degree of freedom joint for allowing bending or stretching is provided at a connecting portion between a distal phalange section 7 and a middle phalange section 9. Then, a driving mechanism for causing this joint to make a rotating motion within a predetermined angular range is provided. This driving mechanism 14 is constituted by a motor 15 for driving the joint and a speed reducer 17. The motor 15 is included in the middle phalange section 9 and generates a driving force for rotating the joint. The speed reducer 17 reduces a speed of the motor 15 and transmits the reduced speed to the joint. The joint and the driving mechanism 14 are configured so that the distal phalange section 7 is rotated relative to the middle phalange section 9 in two directions, namely, an inward direction and an outward direction within the predetermined angular range from a state where the distal phalange section 7 is arranged in a straight line with the middle phalange section.

A finger cover for providing additional friction when handing paper and protection a user's fingernail is provided. The finger cover includes an elongated tubular sleeve having open ends for receiving a user's finger, whereby the open ends accomodate users with long fingernails; and a gripping surface on an outer surface of the tubular sleeve for providing additional friction when handing paper. The invention also includes a fingernail protection portion held in place by the sleeve. The fingernail protection portion is substantially planar in shape and includes a horizontal slit located between its ends for insertion of a user's fingernail therethrough.

Glove for use in collecting data for sign language recognition
Provided in the present invention is a glove for use in collecting data for sign language recognition. The glove comprises: multiple azimuth sensors (11 and 11a-11s) arranged on the glove at positions corresponding to the phalanges and metacarpal bones of the hand and used for sensing postures of the hand, and is characterized in that the azimuth sensors are only arranged on the glove at positions corresponding to the phalanges of the hand other than the distal phalange in proximity to the fingertip of at least one finger among the middle finger, the index finger, the ring finger, and the little finger. The present invention reduces the number of the azimuth sensors arranged on the glove at positions corresponding to the phalanges of the hand, thus reducing costs while not affecting detection performance.
