An electronic visual food probe for insertion into and viewing of the interior of a body of food. The distal end of the stem has one or more openings that collectively allow light into and out of the cavity, the opening(s) exhibiting a degree of radial displacement. A light source in the stem illuminates the interior of the food exposed to the opening. An electronic image sensor receives the light reflected from the interior surfaces of the food proximate the opening(s) and generates an elongated color image of the reflected light. An electronic display system displays the elongated color image.

Disclosed are various embodiments for image-based verification of checklist items. In one embodiment, a user request is received to record a temperature reading of a food item using a handheld temperature sensor. In response to the user request, the temperature reading is received and an image of the handheld temperature sensor is captured. The image of the handheld temperature sensor is stored in association with the temperature reading.

Provided is a sensor package in a refrigerator configured to provide information related to refrigerated food. The sensor package may include a body having a mark classified by a type of food allocated to the sensor package and indicating the type of food of a food to which the sensor package is coupled, a battery, an operation switch, a memory configured to store food information corresponding to the type of food corresponding to the mark, a sensor communication module that communicates with a display provided in the refrigerator, a sensing module that senses state information associated with the food, and a sensor control module that controls the sensor communication module to initiate communication between the sensor package and the display of the refrigerator based on the state information sensed by the sensing module.

Temperature-sensor calibrating method enables reusing the thermometer main unit of a wearable clinical thermometer. The temperature sensors are designed to be detachable from/reattachable into the thermometer main unit, and have an associated information-recording medium. The method calibrates the temperature sensor whenever a temperature sensor is substituted in, enabling the temperature sensor alone to be made disposable. The temperature-sensor calibrating method includes acquiring base resistance values having been sampled on a per-temperature-sensor basis inside a constant-temperature tank; computing for the temperature sensor, based on the difference between the base resistance values and resistance values derived, utilizing the B constant, from actual temperatures gauged with a standard temperature gauge inside the constant-temperature tank during the sampling, a value designating a calibration coefficient; recording in the information-recording medium the value designating a calibration coefficient; and causing a terminal to read in the value designating a calibration coefficient from the information-recording medium.

A wearable sensor device includes a temperature and humidity sensor that measures ambient environmental information around a living body. The temperature and humidity sensor is provided on an outer wall surface of a housing or provided to be separated from the outer wall surface. The outer wall surface of the housing faces a left or right side or diagonally downward when the wearable sensor device is attached to the living body and the living body is in a standing posture.

The present disclosure provides a temperature detection system arranged in a temperature detection device, and a charging device thereof. The temperature detection system includes a power supply, a Bluetooth chip configured to detect a temperature of an object to be measured, output detection pulses and including a thermistor module that is configured to detect an ambient temperature of the object to be measured to obtain an intermediate temperature value, and a pulse temperature sensor arranged around the Bluetooth chip. The Bluetooth chip is configured to receive the detection pulses, determine a final temperature value according to the intermediate temperature value and number of the detection pulses per unit time, and convert the final temperature value into Bluetooth signals to output. The present disclosure can ensure detection redundancy and improve detection accuracy, by providing two temperature detections to calculate the final temperature value according to a preset software program.

One or more implementations of the present disclosure relate to a wireless, multi-sensor food thermometer that includes a temperature probe having a linear array of temperature sensors that are operative to measure: temperature profiles within a food product during a cooking process, a temperature at a core of the food product, a temperature at the surface of the food product, and a temperature of the ambient cooking environment in which the food is being cooked. The temperature probe includes a wireless interface that transmits temperature information to one or more external devices for use thereby. Rather than transmitting raw temperature data, the temperature probe may transmit coefficients that correspond to a function that describes the temperature profile within the food or parameters necessary to solve a governing heat equation, which reduces data transmission requirements and reduces power consumption. The food thermometer may include a charger case that houses the temperature probe and charges a power source of the temperature probe using a replaceable battery.

Environmental control system diagnostics and optimizations using intelligent lighting networks are provided. One or more intelligent lighting modules (ILMs) can be deployed in intelligent lighting fixtures, intelligent lighting zone controllers, and other intelligent lighting network devices to collect ambient environmental data (e.g., temperature, pressure, and humidity) in addition to occupancy and ambient light sensing used for lighting control. In this manner, embodiments of the present disclosure address diagnostics and improve performance of environmental control systems (e.g., heating ventilation and air conditioning (HVAC) systems) by offering a secondary set of sensors for HVAC systems at a lower cost than traditional approaches. In particular, the ILMs or other processing circuitry in communication with the ILMs analyze the collected ambient environmental data to diagnose the health and function of the environmental control system, and communicate the diagnoses to users and/or the HVAC system.
