Abstract: Techniques are provided herein to allow more than a fixed number of radio access point devices to be deployed within a macro cell. At a controller apparatus, a registration request is received from a radio access point device configured to operate in a wireless network to serve one or more wireless client devices in the wireless network in respective relatively small coverage areas. The registration request comprises a macro cell identifier associated with a macro base station apparatus configured to operate in the wireless network to serve one or more wireless client devices in a relatively large coverage area, a radio access point cell identifier associated with the radio access point device, and a particular primary scrambling code selected for use by the radio access point device. When the particular primary scrambling code is not available for use, methods are provided to allocate it in a shared manner but without degrading handover service.

Abstract: An adaptive transmission selection technique is provided. A retransmission scheme is selected for a multiple-input-multiple-output wireless system. A plurality of communication techniques is provided for when a first device needs to retransmit a signal to a second device. The first device determines when the original signal, transmitted to the second device using beamforming techniques, needs to be retransmitted to the second device. If a retransmission is needed, the first device determines channel conditions with respect to the second device. The first device selects a retransmission scheme from a plurality of transmission schemes based on the channel conditions for retransmitting the signal. A first retransmission technique is selected when the channel conditions are static. A second retransmission technique is selected when the channel conditions are relatively slowly changing, and a third retransmission technique is selected when the channel conditions are relatively quickly changing.

Abstract: A power-saving wireless input device and an associated system are included. The wireless input device comprises an antenna, an RFID transponder, an energy-storing unit, and a sensing unit. The RFID transponder receives an AC signal via the antenna, and converts the AC signal into a DC signal. The energy-storing unit receives the DC signal for charging. The sensing unit, which is powered by the energy-storing unit, generates an input signal to the RFID transponder. The RFID transponder demodulates the AC signal to generate a request signal, and performs load modulation according to the input signal to generate a reply signal in response to the request signal. The reply signal is then transmitted via the antenna.

Abstract: A technique for maintaining time synchronization between network nodes involves broadcasting a timing signal from a source node to its neighbors. The timing signal is transmitted in a dedicated source time slot of a super epoch comprising a number of epochs each having a number of time slots. A reply timing signal is received at the source node from a neighboring node designated as the destination node, where the reply timing signal is received in a dedicated destination time slot of the super epoch. The clock drift and propagation delay between the source and destination nodes are computed at the source node. At the neighboring nodes other than the destination node, clock drift can be computed using previous estimates of propagation delay. RTS and CTS exchanges from PTP packets can also be used to estimate the propagation delay in the source node and the clock drift in the destination node.

Abstract: An insulating glass pane structure including two glass panes is formed by providing an elastoplastic strip from a delivery reel, where the elastoplastic strip has a varying dimension along its width including a first, nominal width section and a second, reduced width section that is smaller in width than the nominal width section. Side surface area portions of the nominal width section of the strip are coated with a first adhesive glue, and side surface area portions of the reduced width section of the strip are coated with a second adhesive glue that is diffusion-proof against water vapor. One side surface of the strip is pressed against a first glass pane to form a spacer, the strip being pressed close to an edge of the first glass pane, and the second glass pane is applied and pressed to form the glass pane structure.

Abstract: A method for controlling a model railroad stationary switch machine comprising sensing whether a train occupies a main track section near a track switch that connects between said main track section and at least two diverging track sections. An automatic switch control function for the track switch is inhibited in response to sensing that a train occupies the main track section near the track switch when a train is determined to be approaching the track switch on at least one of the diverging track sections. In addition, a method is provided for controlling a model railroad track switch comprising changing a position of the track switch, and automatically returning the track switch to a home position after expiration of a time interval following the changing of the track switch position.

Abstract: A coaxial phase shifter for very high RF-powers includes an optionally-cooled housing which forms the outer conductor and in which a substantially U-shaped inner conductor made of a tube is arranged which comprises at each of its ends a cooling medium connection for guiding through a cooling medium. The U-shaped inner conductor is externally displaceable for changing its electrical length between a contact-making input-side inner-conductor connection piece and a contact-making output-side inner-conductor connection piece. The inner-conductor connection pieces are disposed coaxially in the outer connection flanges which make contact with the housing.
