Abstract: A network system receives a service request sent from a computing device of a user. The service request identifies a service to be provided by a provider and a service request location. In response to receiving the service request, the network system identifies a plurality of candidate locations. The network system selects the location from a plurality of candidate locations according to predetermined criteria including a frequency measurement of each candidate location. The network system replaces the service request location with the selected location. The network system sends the selected location to the computing device. Responsive to receiving an acceptance of the selected location from the computing device, the network system generates navigation instructions for the provider from a current location of the provider to the selected location.

The food delivery container has an internal volume, an opening, a cover to cover the opening to prevent access, and uncover the opening to allow access, a device for securing the cover and a sensing device for detecting whether the cover, after being positioned to cover the opening, is (still) secured over the opening, in reliance upon a state of the device for securing. The device for securing first implements a pairing or synchronizing operation with the cell phone. If the sensing device detects that the cover is not secured over the opening by the device for securing, after first being secured and armed thereon, the cell phone determines whether an authorized access has occurred.

The system may also help the caregiver to perform rounding tasks. The system comprises a server in communication with the patients' beds and one or more mobile electronic devices (e.g. smart phones). The mobile devices receive answers to a plurality of fall risk questions and forward them to the server. The server generates a patient fall risk assessment from the answers, determines a desired state for fall-risk components of the bed if the patient fall risk assessment indicates the patient has a high risk of falling, compares the states of the fall-risk components to corresponding desired states, and issues an alert at the mobile device if any of the fall-risk components are not in their desired state.

Abstract: A patient support apparatus includes a first transceiver adapted to wirelessly communicate with a second transceiver of a headwall interface that is positioned off of the patient support apparatus. A communication link is automatically established between the first and second transceivers without requiring a user of the patient support apparatus to activate a designated control and without requiring the user to identify the headwall interface. The first transceiver includes a unique identifier assigned to the headwall interface in its messages to the headwall interface. The first transceiver may also automatically transmit a disconnect signal to the headwall interface indicating the termination of the communication link is not accidental. The disconnect signal is sent based on one or more of the following: (1) a brake being off, (2) an A/C power cord being unplugged; and/or (3) a signal strength between the transceivers decreasing.
