## Abstract

An item drop box sensor system for detecting items deposited within a drop box may be configured to detect movement of an item deposit tray and to detect items deposited within the drop box. The drop box sensor system may comprise one or more tray movement sensors for detecting movement of the deposit tray, one or more item detection sensors configured to detect items passing into the drop box via the deposit tray, and an onboard controller for selectively activating the various sensors to conserve power and for transmitting data indicative of the status of the drop box to a central server configured for scheduling item pickups for various geographically spaced drop boxes.

## Claims

### Claim 1

An item drop box comprising:
a housing configured to receive one or more items;
a movable deposit tray for placing items in the housing; and
a sensor system comprising:
one or more tray movement sensors configured to detect movement of the movable deposit tray;
one or more item detection sensors configured to detect items deposited in the housing; and
an onboard controller comprising at least one non-transitory memory storage medium, one or more processors, and one or more wireless transmitters, wherein the onboard controller is configured to:
detect, via the one or more processors, signals generated by the one or more tray movement sensors;
upon detecting movement of the movable deposit tray, activate, via the one or more processors, the one or more item detection sensors;
generate, via the one or more processors, status data for the drop box, wherein the status data identifies a status of the sensor system; and
transmit, via the one or more wireless transmitters, the status data to one or more external computing entities.

### Claim 2 (depends on 1)

The item drop box of claim 1, wherein the one or more tray movement sensors comprises a proximity sensor configured to determine whether the movable deposit tray is in a closed position or an open position.

### Claim 3 (depends on 2)

The item drop box of claim 2, wherein the one or more tray movement sensors comprises an accelerometer configured to detect an angle of rotation of the movable deposit tray.

### Claim 4 (depends on 3)

The item drop box of claim 3, wherein the onboard controller is further configured to:
detect signals generated by the proximity sensor;
upon detecting that the movable deposit tray has moved from the closed position to the open position, activate the accelerometer to detect the angle of rotation of the movable deposit tray; and
upon detecting that the movable deposit tray has moved to a trigger angular position, activate the one or more item detection sensors.

### Claim 5 (depends on 1)

The item drop box of claim 1, wherein the one or more tray movement sensors comprises an accelerometer configured to detect an angle of rotation of the movable deposit tray.

### Claim 6 (depends on 1)

The item drop box of claim 1, wherein the one or more item detection sensors comprises a time-of-flight sensor.

### Claim 7 (depends on 1)

The item drop box of claim 1, wherein activating the one or more item detection sensors comprises activating the one or more item detection sensors for a predefined period of time.

### Claim 8 (depends on 1)

The item drop box of claim 1, wherein the status data identifies whether an item is present within the housing.

### Claim 9

An item drop box sensor system comprising:
one or more tray movement sensors configured to detect movement of a drop box deposit tray and to generate a movement signal upon detection of movement of the drop box deposit tray;
one or more item detection sensors configured to detect items deposited in a drop box housing; and
an onboard controller comprising at least one non-transitory memory storage medium, one or more processors, and one or more wireless transmitters, wherein the onboard controller is configured to:
detect, via the one or more processors, signals generated by the one or more tray movement sensors;
in response to the detected signals upon from the one or more tray movement sensors, activate, the one or more item detection sensors;
generate, via the one or more processors, status data, wherein the status data identifies a status of the sensor system; and
transmit, via the one or more wireless transmitters, the status data to one or more external computing entities.

### Claim 10 (depends on 9)

The item drop box sensor system of claim 9, wherein the one or more tray movement sensors comprises a proximity sensor configured to determine whether the drop box deposit tray is in a closed position or an open position.
