1. List of Components 1.1 UCD SENSOR Unattended Child Detection (UCD) sensors are mounted on the bus or van head liner above alternating seat benches after inserting the UCD into the Senor Housing holder (see Section 1.2). The position and total number of UCD sensors depends on the height and vehicle size. The top side of each sensor is labelled with Software version, Frequency used and Node number of the UCD.
1.2 Sensor Housing The UCD Sensors are secured within the sensor housing before installing on the vehicle. It has a ‘U’ shaped notch on both sides (circled in red in Figure 2 below). Depending on convenience, one of these notches will be cut out to route the wiring to the sensor. The LIN network harness must be connected to the UCD sensor before installation of the sensor and its housing to the vehicle. The housing has a custom locking mechanism that holds the sensor.
Antenna Interface Power and Ignition Connector USD Power and LIN harness Connector User Interface Connector Figure 3:Central Control Unit 1.4 Driver interface User Manual The Driver Interface is a small cylindrical unit mounted on the dashboard or any other driver accessible area that does not obstruct the driver’s vision of the road. The module is connected to the CCU unit with a long wire harness. The wiring will be routed through the existing panelling to prevent any damage or tampering.
1.5 T Harness The T-Shaped wiring harness is used to interface individual sensors to the LIN network. One T- harness is used to connect one sensor to the LIN network. A system with ‘n’ number of sensors will need ‘n’ number of harnesses. The horizontal side of the ‘T’ harness will have a male connector on one side and female on the other. The vertical line of the ‘T’ connects to the sensor head. Female Connector Male Connector Sensor Connector Figure 5: T Harness 1.
LiDAS system battery is connected in parallel to the vehicle battery and connected to the CCU. This battery provides necessary power for the CCU. The battery is also located inside the housing. Use 12 V, ODYSSEY PC545 battery.

Figure 8: CCU and Battery Housing 1.9 Bracket The bracket holds the CCU and Battery housing to the vehicle using fasteners and screws. It provides a solid attachment of housing to the vehicle body and securely holds the CCU and LiDAS system battery modules without movement in the housing. Figure 9: Housing Bracket 1.

LiDAS system must be installed in such a way that using minimum number(One UCD cover two seat rows separated at a distance of 35 Inches) of UCDs the system should cover total passenger volume and detection field must be within the bus to avoid false detection outside the bus. Figure 11 shows the typical orientation of UCD sensor on school bus. The sensor and its housing should install length wise parallel to the windows and transceiver antenna position of a sensor should be exactly above the seat back rest.
Figure 12: Detection field of single UCD Step 2: Find an appropriate non-intrusive location for the CCU and battery housing A typical location for the CCU and battery housing is behind the driver seat. Other nonintrusive locations may also be utilized, such as under the first passenger seat behind the driver.
