Abstract: A method is provided for receiving a wireless message in a mobile telecommunication system. This may include a mobile station (MS) receiving a wireless message. A judgment may be made whether the received message is a general SMS message or a SMS message for a MMS. The message may be directly stored if the received message is a general SMS message. The user may then be informed of a message reception. The RR connection may be released when the received message is a SMS message for a MMS. A flag setting may then be performed. The RR may be reconnected and the second message may be received. These options may be repeated until the second message is received. The two SMS messages may be decoded and formed into one message when the second message for a MMS is received. The message may be stored, decoded and the user may be informed of a message reception. The RR connection may be released, the flag setting may be changed and a RAU processing may be performed.

Abstract: A system and method for minimizing the gap in service during the reception of an MBMS session due to the reselection of a neighboring cell in which that MBMS session is not ongoing, wherein a mobile station (MS) indicates its target cell and MBMS service id (i.e., BSIC, neighboring cell index, and Temporary MBMS Group Identity (TMGI)) to a network by sending this information to the network in an RLC/MAC message, e.g., a packet downlink ACK/NACK or with a new message. If the network has resources available for allocation, the network is permitted to allocate these resources for the MBMS session indicated by the MS and send corresponding MBMS neighbor cell information to the MS upon receipt of the packet downlink ACK/NACK or the new message. When the MS receives the MBMS neighbor cell information, it will then reselect to the target cell identified by the MBMS neighbor cell information.

Abstract: An automatic channel selection (ACS) process enables an access point to determine a best channel available, i.e., the channel with a least amount of interference, for it operation. When ACS is enabled, the access point scans frequencies for all neighboring access points and their signal strengths. Based on this data, the access point then determines which frequency is least likely to be interfered with by these other access points. The access point switches itself to this frequency and begins operation. During normal operation, the access point may periodically rescan the air space and reevaluate its current operating channel. Preferably, every neighboring access point has its own channel, and the co-channel interference levels should be low enough so that there is a maximum coverage and high throughput for the network. If these characteristics cannot be achieved, the access point may then adjust its power automatically to reduce the interference level in the network.

Once a data session is established, the control channel may be idled periodically to conserve power. Alternatively, the protocol utilized in the wireless data session may be used to transmit control messages using the protocol of the present invention.

Abstract: By executing a ring-tone determination program and so on, a handsfree device transmits range information to a mobile phone handset connected with the handsfree device. When the handsfree device receives information of frequency ranges used by ring-tone signals in the handset, it makes a determination according to the received information. If the received information indicates that the handset is compatible with the range information, it transmits a signal for directing not to restrict a frequency range. If the received information indicates that the handset is not compatible with the range information, it transmits either of a signal for directing to restrict a frequency range or a denial signal denying the reception of ring-tone sound, depending on a setting in the handsfree device.

Abstract: An AM/FM modulation scheme is presented for optimizing communications between a remote control device held by a user and a receiving unit installed in a vehicle. Historically, these systems communicated with amplitude modulated signals having good range but poor immunity to ambient random radio frequency noise. Frequency modulated systems provide improved immunity to noise however at the expense of range. The object of this invention is to use two or more modulation modes to combine their advantages. A scheme has been devised whereby circuitry capable of alternately operating in at least two modes is used. The same information is therefore transmitted using two or more modulation techniques in succession. The receiving unit also has circuitry and has listening cycles ensuring eventual synchronization with the transmitting unit. If one mode fails due to distance or ambient noise, the other can then attempt to establish a link.

Abstract: User equipment (UE) in a cellular telecommunications system is operated such that the UE begins operating in a power saving state when a first set of predefined criteria have been satisfied, and leaves the power saving state when a second set of predefined criteria have been satisfied. Determining satisfaction of the first set of predefined criteria includes making a plurality of signal quality measurements of a signal received from a serving cell in the telecommunications system, and making a plurality of signal quality measurements of a signal received from one or more neighboring cells. A first trend line is determined from the signal quality measurements of the serving cell, and a second trend line is determined from the signal quality measurements of the one or more neighboring cells. The first set of predefined criteria are considered to have been satisfied if the first and second trend lines are not converging.

Abstract: The invention is directed to a material and a method of substantially eliminating destructive low-temperature, humidity-enhanced phase transformation of yttria-stabilized zirconia in general, as well as eliminating low-temperature degradation of yttria-stabilized tetragonal zirconia polycrystalline ceramic (Y-TZP). The martensitic-type phase transformation from tetragonal to monoclinic is accompanied by severe strength degradation in a moist environment at low-temperature, specifically at room temperature as well as at body temperature. This class of materials has been chosen as the packaging material for small implantable neural-muscular sensors and stimulators because of the high fracture toughness and high mechanical strength. This destructive phase transformation has been substantially eliminated, thus ensuring the safety of long-term implants, by subjecting the sintered components to post-machining hot isostatic pressing, such that the average grain size is less than about 0.5 microns.

Abstract: Dividing cells within living tissue that contain polarizable intracellular members can be destroyed using at least two insulated electrodes and an electric field source that applies an alternating electric potential across the conductors within the insulated electrodes. The electric field is transformed into a non-homogenous electric field that produces an increased density electric field in a region of the dividing cells. The non-homogenous electric field is of sufficient intensity to cause the intracellular members to be drawn to that region, which causes a pressure increase that results in a structural breakdown of the dividing cells.

The electrical voltage is applied in the form of pulses to the pair of electrodes, thereby stimulating the vagal nerve. The pattern of that stimulating pulses can be varied in response to characteristics of the atrial fibrillation or the ventricular contractions.
