A multilayer time indicator comprises a multilayer first part and a multilayer second part. The first part comprises a topsheet in contact with an enhancement layer and an optional reference layer, and the enhancement layer is in contact with a timing layer. The second part comprises a dye layer, an optional dark layer, and a substrate layer. The timing layer and the dye layer are separate from one another, and are optionally protected by one or more release liners. To activate the indicator, the timing and dye layers are separated from the one or more release liners and then joined to one another.

The present disclosure describes an electrical cable accessory system for covering an electrical cable and/or cable connection. The electrical cable accessory system includes a pre-expanded cable accessory unit and a time-temperature indicator associated with the pre-expanded cable accessory unit. The pre-expanded cable accessory unit includes a pre-expanded cable accessory formed of an elastomeric material and a removable holdout mounted within the elastomeric cable accessory, wherein the holdout is operative to maintain the elastomeric cable accessory in an expanded state and to permit the elastomeric cable accessory to elastically contract when the holdout is removed from the elastomeric cable accessory. The time-temperature indicator is configured to undergo a visible change in appearance in response to a cumulative heat exposure and signal to a viewer when the elastomeric material of the pre-expanded elastomeric cable accessory unit has experienced a threshold cumulative heat exposure. Methods including the same are also described herein.

An athletic timing device includes a housing carrying a touch-less sensor. The device is self-contained and can be easily placed at generally any point on a surface used for athletic activities, e.g., a football field, basketball court, or a track. The collective design of the sensor and the housing facilitates activation of the sensor without interfering with normal athletic activities, i.e., activities can be performed and timed under normal conditions without physical contact between the timing device and objects involved in the athletic activity. Example activities that can activate the sensor include snapping a football, kicking a soccer ball, or sprinting away from (or back to) the device.

Method and system are provided for customer table service management. The method includes receiving sensor load data over time from a customer table. The method analyzes the sensor load data during a waiting time between a time of one or more customers arriving at the table and a time of consumables being served to the table to learn background noise data of the one or more customers. The method further analyzes the sensor load data during a dining time after the time of consumables being served to the table to detect one or more events that require a service action, wherein analyzing the sensor load data during the dining time removes the learnt background noise data to distinguish sensor load data changes relating to consumption of the consumables on the table. The method outputs event detection notifications to prompt the required service action.

A control apparatus includes: a controller configured to estimate a vacant time period during a period from a first time at which a first user checked-in at an accommodation facility to a second time at which the first user is to check-out from the accommodation facility, the vacant time period being a time period during which the accommodation facility is not used by the first user; and a communication interface configured to transmit vacancy data that indicates the vacant time period estimated by the controller, to a terminal apparatus of at least one second user that is different from the first user.

A system for estimating remaining cooking time obtains a target temperature, obtains an ambient temperature value, and receives a plurality of inner temperature values based on temperature data obtained by a relevant inner temperature sensor at a plurality of different timepoints. The system also calculates a plurality of natural logarithm values including, for each particular inner temperature value of the plurality of inner temperature values, a natural logarithm of a difference between the ambient temperature value and the particular inner temperature value. The system also determines a linear regression line that models a relationship between the plurality of natural logarithm values and the plurality of different timepoints, obtains a slope value and an interception value based on the linear regression line, and determines a remaining time based on the interception value, the slope value, and a natural logarithm of a difference between the ambient temperature value and the target temperature.
