  • Patent number: 11349561
    Abstract: Systems are disclosed for a communication system optimized for low data volume communications. In embodiments of the invention, a terminal in the communication system is configured to send and a receiver in the network infrastructure is configured to receive bursts containing pilot waveforms that include time spacing and/or phase changes between short sequences. The time spacing and/or phase changes can be selected to reduce out-of-phase autocorrelation and achieve robust performance.

  • Publication number: 20220103249
    Abstract: Systems are disclosed for a communication system optimized for low data volume communications. In embodiments of the invention, the energy used to transmit an acknowledgement message differs depending on whether the acknowledgement is an ACK or a NACK. The energy used to transmit an ACK is set to be significantly less than the energy used to transmit a NACK. Preferably, the energy used to transmit the acknowledgement message is negligible if the acknowledgement message is an ACK compared to if the acknowledgement message is a NACK. In one embodiment, the energy used to transmit an ACK is set near zero and the energy used to transmit a NACK is set approximately four times the energy of an acknowledgement message if the energy required to transmit a NACK and an ACK were equal.

  • Patent number: 11115116
    Abstract: Systems are disclosed for a communication system optimized for low data volume communications. In embodiments of the invention, a terminal in the communication system is configured to receive beam shape information from a satellite and use the beam shape information for calculating the terminal's initial transmit power based on the beam shape information. The terminal can also determine the terminal's location and calculate an achievable information data rate of transmitted bursts based on the beam shape information. The terminal can also determine an estimated terminal position based on correlating signal-to-noise ratio measurements on the camped beam and at least one neighbor beam neighboring the camped beam.

  • Patent number: 11103096
    Abstract: The secure parcel delivery receptacle comprises a parcel receptacle, a locking cover, a scanner, and a camera. The parcel receptacle may be a container into which the parcel may be placed. Access to the parcel receptacle may be via the locking cover which may only be unlocked by the scanner. The scanner may scan the parcel using wireless technology, optical technology, or a combination thereof to determine parcel identification information from the parcel. The parcel identification information may comprise or may be associated with a one-time code that will unlock the locking cover one time only. The camera may record one or more images as proof of delivery. The scanner may transmit one or more wireless messages containing status information regarding attempts to access the secure parcel delivery receptacle to the purchaser, to the seller, or to both.

  • Patent number: 10193616
    Abstract: A system and method are disclosed for a communication system optimized for low data volume communications. In embodiments of the invention, a terminal in the communication system sends a burst comprising a message to network infrastructure in the system at a pre-scheduled time such that the network infrastructure can derive a terminal identity for the terminal by the time of the burst without having to include terminal identity information in the message. The bursts are intended to communicate a message without all of the overhead used in establishing and terminating a connection associated with convention communication systems. The bursts are sent in predetermined formats, at predetermined times so that the identity of the terminal can be easily determined eliminating the need for much of the overhead of a conventional MSS.

  • Patent number: 9973264
    Abstract: A method for synchronization of user terminal (UT) uplink data transmissions to a satellite in a satellite communications system is provided. The UT tracks frame timing and frequency of downlink data transmissions received by the UT from the satellite. The UT estimates a respective timing delay and frequency shift of the downlink data transmissions based on the tracked frame timing and frequency of the downlink data transmissions. The UT receives satellite ephemeris data broadcast by the satellite. The UT synchronizes uplink data transmissions to the satellite based on the estimated timing delay and frequency shift of the downlink data transmissions, the received satellite ephemeris data, and knowledge of a UT position and velocity vectors associated with any movement of the UT.

  • Patent number: 9749035
    Abstract: A synchronization approach is provided that compensates for the large Doppler offset of the satellites in a LEO satellite system by exploiting the predictable and deterministic nature of the Doppler component, and thereby simplifies the delay and the Doppler domain uncertainty ranges that the physical layer receivers have to resolve. The compensation is based on the known ephemeris information of the LEO satellite and the known positions of the gateway (GW) and the user terminal (UT) on the ground. Utilizing the deterministic component of the LEO Doppler, the synchronization process continually tracks and compensates for the time-varying offsets between the GW and UT frame timing, frame numbering (FN), symbol timings, and Doppler-induced scaling of center frequency and the signal bandwidth.

  • Patent number: 7245930
    Abstract: A method for enabling synchronization of a communications terminal in a wireless communication system, and a corresponding acquisition system of the communications terminal, wherein the method consists of the steps of: receiving a burst at a receiver of the communications terminal, the burst containing a composite waveform including two or more component waveforms, wherein each of the two or more waveforms has a known frequency variation throughout the burst; detecting the presence of the composite waveform; and estimating a frequency offset and a timing offset of the composite waveform as received into the receiver, whereby synchronization is achieved.

  • Patent number: 7016444
    Abstract: Filtering loop and method for maintaining synchronization between a receiver and a transmitter reduces overhead and enables more robust operation. The method includes the step of receiving an error signal corresponding to a synchronization parameter. A first order filter is applied to the error signal such that a residual signal results. The method further provides for compensating the residual signal for drift such that the compensated residual signal estimates a rate of change in the residual signal. By compensating the residual signal for drift, difficulties associated with time lag and signal degradation are obviated.

  • Publication number: 20050284391
    Abstract: A circular litter box having a scoop removal remounted in a scoop holder which is pushed around the sidewall of the box to scoop the box. The mounting mechanism for the scoop causes the scoop to assume a relatively vertical position during scooping, to minimize formation of a wave of litter in front of the scoop as it is rotated, but causes the scoop to assume a more horizontal position as the scoop is removed, so the collected waste will not spill from the scoop during removal.
