Abstract:
A process is provided whereby organic carbonyl substrates, including esters, lactones, ketones, amides and imides are reduced in a reaction with a silane reducing reagent and a catalyst. Exemplary catalysts include metal alkoxides and metal aryloxides.
Abstract:
A minimum confidence level is applied to recognize a localizable wireless system debility from a debility which is invariant from place to place or which cannot be significantly distinguished from service performance levels of comparable mobile user terminals in the network as a whole. Reports received by the population of users of a service or product family are scored, aggregated, normalized, and averaged overall and for each geographic service area. A report is received from a particular end user and the customer operated wireless instrument and transformed into an individual user experience score over a length of time and breadth of locations. The reports provided by the population of users are transformed into a population experience score that reflects usage in the same time and locations reported from the wireless instrument of the particular end user. Various potential causations are considered and those which exceed a minimum level of confidence are presented.
Abstract:
A method for operation of a battery consumption analysis server communicatively coupled to a plurality of mobile devices over radio channels to receive packages of data recorded at each mobile device containing application use, and battery charging and discharging events. By receiving independent sets of information from the mobile device wherein independent sets comprise at least one of wireless phone activities and battery use, combining this information in such a way that the battery consumption or over consumption of specific applications are identified, the apparatus and method configures a display to identify the correspondingly bad applications to a user.
Abstract:
A mobile station having a Voice-Over-Internet-Protocol client sends a message proposing a frame packing and frame repeating parameter set (1001). The called client may either accept the proposal or offer a revision (1003). If accepted the VoIP call is established (1009). If a revised proposal is received, it is determined whether the parameters are acceptable (1005). If not the call is declined (1007). If acceptable the call may proceed (1011). Both clients may then monitor network conditions (1013) and propose revisions to the parameters as conditions change. In this way, the VoIP application layer compensates for physical and Medium Access Control (MAC) layer inefficiencies in transporting the small frames used for audio data transfer for VoIP.
Abstract:
Disclosed is a method of and apparatus for increasing the capacity of a wireless communication system. This is accomplished by having users that can support a higher than base modulation order be required to do so under predetermined conditions such as electrical distance from a base transceiver station (BTS) antenna to a user, the reception of data in a high speed burst (HSD) and the like. The same digital processor apparatus that may be used to provide a base order modulation scheme may be reprogrammed in a more complex fashion to provide signal processing at the higher modulation rate for any given user channel.
Abstract:
A new access channel protocol for use in cellular systems such as CDMA whereby the data transfer efficiency of an access message is increased by removing the requirement that a preamble frame and a message capsule frame have equal times of duration. With such removal, the BTS must inform listening MSs as to the time duration of the frames in each of the preamble and the message portions of the access channel time slot in addition to previously supplied information as to the number of frames in each portion. When unequal frame duration times are allowed, each portion of the access channel may be more nearly optimized to the actual time required to perform the functions of synchronization and message detection.
Abstract:
A CDMA communication system supports designated mode data bursts on a reverse link contention based channel from a subscriber unit to a base station. The reverse link contention based channel also supports contention-based transmissions from the subscriber unit to the base station. When transmissions are scheduled and serviced in the designated mode data burst, collisions are avoided. Further, because setting up the designated mode data bursts on the reverse link contention based channel require little overhead as compared to the setup of a traffic channel the CDMA system is operated at a greater efficiency. The reverse link contention based channel may be a Reverse Common Control Channel, a Reverse Access Channel or another contention-based channel. Designated mode data bursts on the reverse link contention based channel may consume a single slot or multiple slots. The number of slots consumed in the designated mode data bursts depends upon the volume of data the subscriber unit has to transmit to the base station. The subscriber unit may state the amount of data it desires to transmit in the designated mode data burst. Based upon this stated amount, the base station may reserve multiple slots for the designated mode data burst. Then, the subscriber unit will transmit data during the slots.
Abstract:
A delay element for fine tuning the position in time of timing edges of an input signal, comprising a first and a second inventer, each comprising a data input, a control input and a data output. The delay element further comprises a node comprised of a connection between the data output of the first inverter and the data input of the second inverter. An adjustable control voltage is included for applying a biasing voltage to the first and second control inputs to thereby control the amount of charge supplied to the node. Finally, the variable capacitance means is connected to the node for applying finite amounts of capacitance to the node to delay and thereby fine tune in time the timing edges of the input signal propagating from the first inverter to the second inverter.
Abstract:
A customer self-service tuning system assists a mobile device user in adjusting his network settings and device configuration. Device, network and performance metrics are stored for a population. Over time all of these suggest changes in the device or network that change measured performance. The potential improvement(s) are presented to the user for selection. Performance measurements are taken and the user can choose to go forward with the new configuration or to revert. Each time a user requests self-care service, a new cohort is extracted from the then current overall population and analyzed for similarity to the user at that point in time. Each time an improvement is selected, the history of device states and network states is augmented. Identified variances are transformed into an action plan specific to a user and implemented on the device or network upon concurrence.
