Abstract: The present invention discloses a trench capacitor formed in a trench in a semiconductor substrate. The trench capacitor comprises a bottom electrode positioned on a lower outer surface of the trench, a dielectric layer positioned on an inner surface of the bottom electrode, a top electrode positioned on the dielectric layer, a collar oxide layer positioned on an upper inner surface of the trench, a buried conductive strap positioned on the top electrode, and an interface layer made of silicon nitride positioned at the side of the buried conductive strap. The bottom electrode, the dielectric layer and the top electrode form a capacitive structure. The collar oxide layer includes a first block and a second block, and the height of the first block is larger than the height of the second block. The interface layer is positioned on a portion of the inner surface of the trench above the second block.

Abstract: A data transmission device is mounted to a wrist exerciser for detecting the rotational speed of a rotor inside the wrist exerciser and generating and transmitting exercising data associated with the rotational speed from the wrist exerciser to an external device. The data transmission device includes a transmitter unit coupled to a casing of the wrist exerciser and having a sensor for detecting the rotational speed of the rotor and issuing a detection signal, and a processing circuit receiving and processing the detection signal to provide an output of the exercising data, including counts of rotation and the rotational speed. A transmission cable has a first end connectable with the output of the processing circuit to receive the exercising data and a second end engageable with a counterpart device of the external device for forwarding the exercising data to the external device.

Abstract: A rotor is rotatably received in a casing to form a wrist exerciser. The rotor includes a spherical body defining a bore in which an inner flange is formed. First and second weight members are received in the bore on opposite sides of the flange. The weight members have inner end portions releasably attached to opposite surfaces of the flange. Through holes are defined in the first and second weight members to receive an axle of which ends project beyond opposite ends of the body to rotatably engage a support ring of the casing.

Abstract: A wrist exercise includes a casing rotatably receiving a rotor therein. The casing defines slots that are aligned in pair. The rotor has axially aligned rotation shafts respectively and rotatably received in holes defined in the casing for rotatably supporting the rotor inside the casing. A drive roller is mounted to one of the rotation shafts. A drive bar is partially and movable received in the casing through the aligned slots to drivingly engage the drive roller whereby by forcibly pulling the drive bar out of the casing, the drive roller is caused to drive an initial rotation of the rotor with a high rotational speed.

Abstract: A wrist exercise includes a casing defining an interior space rotatably receiving a rotor. The casing includes upper and lower casing members. The upper casing member has a first mating edge forming a first mating device. The lower casing member has a second mating edge forming a second mating device for mating the first mating device to attach the lower casing member to the upper casing member whereby a circumferential groove is defined between the first and second mating edges. A first retention ring is at least partially fit over the upper and lower casing members and forms an inwardly-projecting portion fit into the groove to securely retain the upper and lower casing members in position.

Abstract: A power generating machine having a frame provided with a first support, a second support and a third support laterally and adjustably mounted between the first and second supports. A bellows is mounted under the third support and between the first and second supports. The bellows has a buoy mounted at a bottom of the bellows to adapt to be flush with sea level so that sea waves are able to drive the bellows to move up and down reciprocally. A first tube is mounted to communicate with the first tube and so as to allow air to be sucked in the first tube when the bellows extend. A second tube is communicated with the first tube so as to allow air flowing only to a tank connected to and communicating with the second tube to drive a pneumatic generator to generate electricity.

Abstract: A wrist exerciser includes a spherical hollow casing having a top opening. A ring is received within the casing and substantially coincident with a great circle of the casing. A rotor is rotatably received in the casing by being rotatably supported by the ring. The rotor has a circumferential groove defined in an outer surface thereof for receiving a rope wound around the rope. By manually pulling to unwind the rope through the top opening, the rotor is rotated in the casing. A number of light emitting diodes (LEDs) are arranged on the outer surface of the rotor in a predetermined fashion. A power supply device is mounted to the rotor and electrically connected to the LEDs via a microprocessor based control circuit for conducting on/off the LEDs in accordance with operation modes performed by the microprocessor. By making use of the persistency of human vision, a limited number of the LEDs may display complicated messages, including the rotational speed of the rotor.

Abstract: The invention relates to an arrangement (100) comprising a mobile device (110) and an auxiliary rendering device (120). The mobile device (110) receives content from a content server (101) via a transcoding proxy (104) and can render it by itself, or relay it to the auxiliary rendering device (120). The mobile device (110) adapts the primary communication session to the capabilities of the auxiliary rendering device (120). Preferably the mobile device (110) receives an assistance message comprising information on the capabilities of the auxiliary rendering device (120), and relays this to the transcoding proxy (104) so that the content can be transcoded to a format suitable for the auxiliary rendering device (120). The mobile device (110) can perform a handover to a second auxiliary rendering device (121) if necessary.
