Title: Frequency hopping sounder signal for channel mapping and equalizer initalization
Inventor: HENRY SPYKER OWEN
IPC: E21B47/18
Filed: 2015-07-24
Abstract: A system for channel sounding and initializing an equalizer using a frequency hopping sounder signal. The system identifies a frequency range for sounding a channel between a first device at a first location within a wellbore and a second device at a second location within the wellbore. Center frequencies, bandwidths, and timeframes are assigned to each of a plurality of sounding sequences, such that an entirety of the frequency range is assigned to the plurality of sounding sequences, and wherein when played in order according to the timeframe assigned to each sounding sequence in the plurality of sounding sequences, a sounding signal having a non-contiguous frequency is produced. By comparing an attenuated sounding signal based on the sounding signal to the sounding signal, the system estimates a transfer function of the channel. The system also initializes the equalizer based on the comparison.

Title: A system and method for providing last mile mobility vehicle to a user
Inventor: THOMAS WINKLER
IPC: G08G1/0968
Filed: 2020-03-06
Abstract: A method for providing a last mile vehicle service to a user. When the user starts a trip, a processor detects the user’s current and destination location data. The user may be notified of a parking location based on the traffic conditions so they can switch to a last mile vehicle service. Based on the location data, a plurality of last mile service providers are identified, each having a number of vehicles such as e-bikes, e-scooters and small cars. Distances between the user and the last mile service providers are determined. Travel times from the last mile service providers to the user destination are determined based on the type of vehicles at respective service providers. An optimal last mile service provider is selected based on the determined distances and travel times. Once the user arrives at the selected last mile service provider, the user destination data is synchronized into a device of a vehicle of the service provider.
