Patent number: 12238820Abstract: A system is described in which a default mobility management entity (MME) receives, from a base station, a request for setting up a communication connection to a mobile device having an associated usage type. The default MME sends, to the base station and responsive to the request, a message identifying a dedicated MME, to which the request should be re-routed, the dedicated MME having a supported service type corresponding to the usage type associated with the mobile device. The base station sends a response to the default MME, the response indicating whether re-routing to said dedicated MME is was successful or not (e.g. due to an overload of the dedicated MME). If the re-routing was not successful, the default MME attempts to serve the mobile device instead of the dedicated MME.Type: GrantFiled: March 14, 2022Date of Patent: February 25, 2025Assignee: NEC CORPORATIONInventor: Sivapathalingham Sivavakeesar

Patent number: 11990932Abstract: A clock buffer or driver is gated pending reception of verifiable crypto keys. These clock buffer or divers remain gated, thus disabling a processor from any meaningful function, till crypto keys are decoded, verified, and applied to the clock buffer or driver. A low frequency pseudorandom frequency hopping time sequence is generated and used for randomizing spread-spectrum to modulate a reference clock (or output clock) of a frequency synthesizer. This hopping time sequence holds the key to unlocking the crypto keys. The PWM modulated crypto keys are carried by the hopping time sequence. To decode the PWM modulated crypto keys, the hopping time sequence is used. The reference clock which is modulated with crypto keys in the spread-spectrum is sent to a decoder (in a processor) along with the hopping time sequence. The crypto keys are decoded and then used to un-gate the clock buffer.Type: GrantFiled: December 23, 2020Date of Patent: May 21, 2024Assignee: INTEL CORPORATIONInventors: Mohamed A.

Patent number: 11863367Abstract: Multimedia codecs (compression methods), based only on FFT (Fast Fourier Transform) have been recently proposed. These codecs use the largest points (foreground) and the most energetic bands (background). Medium quality versions are based on the largest local peaks only. The phases can be ignored with the largest local peaks or in the background. Alternatively, sine and cosine amplitudes can be used. This invention describes methods for giving utility to the reintroduced phases, in particular: local peaks are grouped to have a very narrow bandwidth, with the phases containing the displacements of these peaks, and we transport data and the points of the foreground in the phases of the background. High speed communications are supported using techniques similar to OFDM (Orthogonal Frequency-Division Multiplexing). These processes are intended to be used in particular with connected objects and in the physical layers of computer networks.Type: GrantFiled: August 20, 2021Date of Patent: January 2, 2024Inventor: Georges Samake

Patent number: 11405026Abstract: Embodiments of the present disclosure provide systems and methods of reducing the EMI effect generated by such analog blocks. By varying the clock frequency in time of oscillators used by such analog blocks, the EMI energy may be spread over a wide spectrum range thereby reducing the peak energy for the main frequency. To achieve this, the oscillator frequency is directly varied using analog mechanisms. The mechanisms may be based on a synchronized method for increasing/decreasing the current that is charging/discharging the oscillator capacitor. The frequency variation may be achieved by analog control of the extra charge/discharge current.Type: GrantFiled: January 29, 2021Date of Patent: August 2, 2022Assignee: Infineon Technologies LLCInventors: Oleg Dadashev, Yoram Betser

Patent number: 11394424Abstract: Ultra-Wideband (UWB) technology exploits modulated coded impulses over a wide frequency spectrum with very low power over a short distance for digital data transmission. Such UWB systems through their receivers may operate in the presence of interfering signals and should provide for robust communications. Accordingly, an accurate and sharp filter that operates at low power is required and beneficially one that does not require a highly accurate power heavy clock. Further, many UWB applications require location and/or range finding of other elements and it would therefore be beneficial to provide a UWB based range finding and/or location capability removing the requirement to add additional device complexity and, typically significant, power consumption.Type: GrantFiled: March 15, 2021Date of Patent: July 19, 2022Assignee: Transfert Plus, Societe En CommanditeInventors: Frederic Nabki, Dominic Deslandes, Mohammad Taherzadeh-Sani, Michiel Soer, Rabia Rassil

Patent number: 11362675Abstract: In a multi-antenna communication system using LDPC codes, a simple method is used to effectively improve the received quality by performing a retransmittal of less data without restricting applicable LDPC codes. In a case of a non-retransmittal, a multi-antenna transmitting apparatus (100) transmits, from two antennas (114A,114B), LDPC encoded data formed by LDPC encoding blocks (102A,102B). In a case of a retransmittal, the multi-antenna transmitting apparatus (100) uses a transmission method, in which the diversity gain is higher than in the previous transmission, to transmit only a part of the LDPC encoded data as previously transmitted. For example, the only the part of the LDPC encoded data to be re-transmitted is transmitted from the single antenna (114A).Type: GrantFiled: January 15, 2021Date of Patent: June 14, 2022Assignee: Panasonic Intellectual Property Corporation of AmericaInventors: Yutaka Murakami, Kiyotaka Kobayashi, Choo Eng Yap
