Revision History

Introduction

This guide provides information on the installation and operation of the Vayyar vSILSA_RevC_CTPB0 Module. vSILSA_RevC_CTPB0 is a three-dimensional mm- wave sensor used as a short-range device for interactive motion sensing. The operational flow, as described in this document, is one realization for the usage of the vSILSA_RevC_CTPB0 device, while other possible realizations could be integrated with a hosting-product, operate in conjunction with various hosts other than a PC, communicate through various API-s and SW environments. All control and operation options preserve the same operation of the device in terms of transmitted RF waveform (output power, bandwidth), according to the regulated values. The device should be installed inside a vehicle cabin, to detect and monitor objects in a defined arena. The module provides a real-time image of objects positions within the arena.
Typical applications for the device can be in-cabin monitoring for detection of infants left in car and more.

Release Information

Sensor Integration instructions

The vSILSA_RevC_CTPB0 shall be installed inside a car’s cabin. There are several potential installation locations inside car’s cabin, which must support both functional performance and are applicable by the conditions of the DA 21-407 waiver. The final product, incorporating the vSILISA_RevC_CTPB0 module, shall be restricted to factory installation in the interior of new passenger motor vehicles for the primary purpose of in-cabin monitoring functions, and shall not be marketed in after-market add-on products.

Adequate installation would be:

1. The sensor connected firmly to the car’s roof, either directly to the metal frame \ plastic bracket on the cabin’s frame, or on top of the headliner.
2. The sensor connected firmly to the car’s A/B/C Pillar, either directly to the metal frame \ plastic bracket on the pillars, or on top of the pillar covers.
3. The sensor is connected firmly to the car seat / headrest either directly to the metal frame or on top of the upholstery.
4. Alternative installation locations may also be possible – as long as the sensor is positioned inside the cabin, according to the conditions of the DA 21-407 waiver.

Examples of installations options:

System Overview

The vSILSA_RevC_CTPB0 is designed to demonstrate Vayyar’s 4D interactive motion sensing, which enables identifying multiple objects (“blobs”) in a defined space (“arena”).

System Architecture

The vSILSA_RevC_CTPB0 system architecture and connectivity scheme is illustrated in the figure below.

The vSILSA_RevC_CTPB0 system is comprised of the following components:

• The vSILSA_RevC_CTPB0 RF Sensor Unit.
• The SW Engine. Host software that performs signal processing functions. The software runs in a command window on a PC, which is connected to the vSILSA_RevC_CTPB0 sensor by a USB cable.
• Web GUI. User-interface client software that communicates with the SW Engine via a TCP/IP connection. The Web GUI client is supported by the following browsers:
  • Google Chrome
  • Mozilla

Digital Interface

The digital interface connects the host PC with the board. The interface is implemented on the board using an MCU and a micro-USB connector. The onboard micro-USB-B 2.0 connector (appears in red in the figure below) is used for data transfer between the sensor unit and the host PC. The connector supports the USB 2.0 protocol in High-Speed Mode (480 Mbps).

Software

The vSILSA_RevC_CTPB0 system software performs signal processing and generation of the arena image. It communicates with the Web GUI by a TCP/IP connection, which displays images and blobs that correspond to the detected objects.

NOTE
The Graphical User Interface supports use of a single sensor only.

Module Outputs

Outputs from the sensor can be presented either through the Web GUI or a corresponding API. The data can be saved as MAT files (compatible with MathWorks MATLAB). The system’s outputs can be further processed or analyzed in parallel to the saving process. The output data is available either in its raw data form or as a 3D/2D image.

Regulatory section

Compliance

FCC

The device is certified under FCC DA 21-407 waiver conditions, as – FCC-ID: 2AHIS-V60GINCAR-SL. This vSILSA_RevC_CTPB0 device has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:
Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. The device shall not be used on an airplane while airborne. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
