An object of the present invention is to provide a sensor unit that can suppress deterioration in communication quality as compared with in the conventional art even when a number of sensor units are connected in sequence, and multiple-type sensor using the sensor unit. A sensor unit in the present invention includes a sensor, and a microcontroller that is electrically connected with the sensor and processes a detection signal of the sensor, wherein the microcontroller includes a host communication control unit that communicates with a host device and a client communication control unit that communicates with a client device. According to the present invention, the deterioration in communication quality can be suppressed as compared with in the conventional art, even when a number of sensor units are connected in sequence.

A device included in a communication system that includes a LoRa endpoint and a LoRa server. Each LoRa frame exchanged between the endpoint and the server has to pass through a meter and a data concentrator included in a first powerline communication network of a system for the automatic management of readings from meters. The meters are attached to at least one data concentrator via the first network. At least one of the meters implements a LoRa gateway that has a communication interface enabling it to exchange LoRa frames with the endpoint. The device is connected to each data concentrator by a second network and to the server by a third network. Each LoRa frame exchanged between the endpoint and the server (1) passes through the device and (2) is encapsulated in a frame according to a frame format that the server will exchange with a LoRa gateway.

The invention relates to a method for operating a sensor arrangement in a motor vehicle (1) on the basis of a DSI protocol, wherein the sensor arrangement (2) has a central unit (3) as a master and a plurality of sensor units (S1, S2, S3, S4, S5, S6) each having a receiver (6) as slaves controlled by the master, and the central unit (3) and the sensor units (S1, S2, S3, S4, S5, S6) are connected to a bus cable (4). In the method, communication takes place via the bus cable (4) between the central unit (3) and the sensor units (S1, S2, S3, S4, S5, S6) in such a way that the master selects whichever slaves are assigned time slots (ZS1, ZS2, ZS3, ZS4, ZS5, ZS6) for sending data. The time slots (ZS1, ZS2, ZS3, ZS4, ZS5, ZS6) are therefore not statically assigned but dynamically assigned. Specifically, it is thus the case that for a particular measurement not all slaves receive an assigned time slot for sending data. Such a method is therefore provided, in which a communication between master and slaves is normally possible with a high bandwidth.

An insulated bag reduces heat exchange between temperature-sensitive items and ambient surroundings. The insulated bag has a bag body which can be covered by a bag lid. The bag lid is provided with a first portion of a securing element. The insulated bag is suitable for insertion into an item space of a mobile delivery robot. The mobile robot has a robot lid provided with a complementary second portion of the securing element. After the insulated bag is inserted into the item space, the two portions of the securing element are connected. Thereafter, when the robot lid is opened, the bag lid is also opened, permitting access to its contents.

A battery management system includes a microcontroller having first and second applications. The first application transitions a contactor to an open operational position if a first CRC diagnostic flag is equal to a first encoded fault value. The second application transitions the contactor to the open operational position if a second CRC diagnostic flag is equal to a second encoded fault value. The first and second encoded fault values have a Hamming distance of at least four from one another.

Aspects of the present disclosure are directed toward power outage assessment using customer-site communication devices which are powered by utility power lines and which communicate with a remotely-situated computer server over a broadband network according to certain schedules. The server can receive from the devices, communications indicative of an operating status of each respective communication device as expected according to the schedules. In response to receiving and/or not receiving the respective communications from the devices and taking into account other parameters, the server can assess a possible power outage within one or more regions by comparing the received communications and threshold criteria associated with the schedules. Based on such criteria, the server can detect and report on conditions suggestive of a power outage in regions associated with the communication devices.
