  • Patent number: 10343423
    Abstract: A microcontroller-based system for identifying a paper type of a sample of paper from a measurement of its electrical impedance. An interdigital dielectric sensor (55) is deployed in the paper path of a printer (PTR), and the electrical impedance at the sensor, as affected by a sheet of paper (P) near the sensor, is measured over a plurality of frequencies of a stimulus signal. The stimulus signal may be sinusoidal or a square wave. The impedance characteristic, in magnitude or phase, or both, is compared against a plurality of reference impedance characteristics, each associated with a paper type, to identify the closest match and thus the type of paper of the sample sheet.

  • Patent number: 10349396
    Abstract: A system and method for providing both localized and distributed transmission modes for EPDCCH is disclosed, where one EPDCCH comprises of one or multiple CCEs. Localized versus distributed transmission may be defined in terms of the EPDCCH to CCE resource mapping. In a localized transmission CCEs are restricted to be contained within one PRB. In a distributed transmission a CCE spans over multiple PRBs. A UE can be configured to either receive the EPDCCH only in localized or only in distributed transmissions. A UE can also be configured to expect EPDCCH transmissions in both localized and distributed transmissions. In each PRB configured by the higher layer as an EPDCCH resource, 24 REs that may be used for any DMRS transmission are always reserved and not used for EPDCCH transmission.

  • Patent number: 10345844
    Abstract: An integrated circuit is provided with a bandgap voltage reference circuit having a bandgap reference voltage output. A bandgap failure detection circuit is coupled to the bandgap reference voltage output. The bandgap failure detection forms a model value of the reference voltage from a first time, compares a present value of the reference voltage at a second time to the model value; and asserts a bandgap fail signal to indicate when the present value is less than the model value by a threshold value. The integrated circuit is reset by the bandgap fail signal. The detection circuit may be operated from a failsafe voltage domain that also allows a critical circuit to complete a pending operation during a reset.

  • Patent number: 10348432
    Abstract: Embodiments of the invention are directed to a cellular communication network that can determine whether communications between one base station-UE pair may interfere with another UE that is in the same cell or a different cell. The network identifies interference parameters associated with interference signals that may be received by a UE. The interference signals may be generated by the base station itself, such as communications with other UEs, or by a neighboring base station. The base station transmits the interference parameters to the UE. The UE receives the one or more parameters comprising information about signals expected to cause intra-cell or inter-cell interference. The UE then processes received signals using the one or more parameters to suppress the intra-cell or inter-cell interference.

  • Publication number: 20190207010
    Abstract: An integrated circuit having silicide block integrated with CMOS transistors is formed by forming a silicide block layer of primarily silicon dioxide, free of silicon nitride and silicon oxy-nitride, at less than 400° C. prior to annealing the PMOS sources and drains. A spike anneal process concurrently anneals the PMOS sources and drains and densifies the silicide block layer. The NMOS drain junctions are less than 120 nanometers; the NMOS halo regions include boron. The NMOS and PMOS transistors are laterally separated by an STI oxide layer. A wet deglaze process prior to metal silicide formation removes less than 25 percent of the silicide block layer, and exposes sides of the NMOS drains less than 20 percent of the drain junction depth. The metal silicide does not extend down the NMOS drains sides, directly adjacent to the STI oxide layer, more than 20 percent of the drain junction depth.
