  • Patent number: 10841559
    Abstract: Three-dimensional (3D) depth imaging systems and methods are disclosed for use in commercial trailer loading. In various aspects, a 3D-depth camera is configured and oriented in a direction to capture 3D image data of a vehicle storage area. A depth-detection application (app) executing on one more processors determines, based on the 3D image data, a void data region, and a floor data region within the 3D image data. Based on the determination of the void data region and the floor data region, the depth-detection app generates an out-of-range indicator that indicates that a wall (e.g., a package wall) situated at a rear section of the vehicle storage area is not detected. The determination that a package wall is not detected causes a dashboard app to modify a graphical representation of the capacity of the vehicle storage area.

  • Patent number: 10816638
    Abstract: Ultrasonic locationing interleaved with alternate audio functions includes a plurality of transmitters for emitting ultrasonic bursts and alternate audio signals. A backend controller schedules the ultrasonic bursts and alternate audio signals from each transmitter. The backend controller can characterize an interference effect of defined interference parameters for each alternate audio signal, with respect to the ultrasonic bursts, and modify interleave scheduling of the ultrasonic bursts and alternate audio signals in accordance with the respective interference effect. A mobile device can receive the ultrasonic bursts for locationing of the mobile device, while a user or other device that can act on information in the alternate audio signals.

  • Patent number: 10803269
    Abstract: First and second photodetectors having first and second collection areas receive return laser light that is reflected and scattered from a target, and generate first and second analog electrical output signals having first and second magnitudes. The second collection area is in close proximity to the first collection area. The first output signal is processed to obtain information related to the target. The first and the second output signals are processed, preferably by determining a ratio of the second magnitude to the first magnitude. A working distance to the target is determined based on the determined ratio. One or more reading parameters by which the target is electro-optically read are adjusted based on the determined working distance.

  • Patent number: 10802108
    Abstract: A technique for non-echo pulsed ranging of a mobile device within an environment includes a plurality of emitters within the environment transmitting signal pulses of a predefined frequency to a mobile device that can receive a signal pulse, convert the signal pulse into a digital waveform, store the digital waveform into a buffer having a predetermined length of time, and analyze the digital waveform to detect a signal pulse at the predefined frequency. If a signal pulse is detected, the mobile device can re-analyze the digital waveform that was stored in the buffer to see if another signal pulse can be detected within the waveform, indicating the existence of a reflected signal. If another signal pulse is detected, the mobile device can select the signal pulse that was received first in time, i.e. the direct signal, for use in ranging of the mobile device.
