A mobile device that includes an input device, an output device, and an electronic processor connected to the input device and the output device. The electronic processor is configured to receive, from the input device, information about a disinfectant and set a threshold time, a threshold activity level, or both the threshold time and the threshold activity level based on the information about the disinfectant. The electronic processor is also configured to track a passage of time, an activity level, or both. If the passage of time is greater than or equal to the threshold time, the activity level is greater than or equal to the threshold activity level, or both then the electronic processor is configured to output a user notification, via the output device.

A sonic generator for use with timing and data collection systems is a button activated device operated by a referee during a live sporting event. It can be hand-held or integrated with a referee's belt pack and replaces a conventional exhalation-powered whistle. It can be configured to record and replay a custom sonic signal, a sonic signal selected from a database of pre-recorded sounds, or a standard sonic signal such as a generic whistle sound. Each sonic generator generates a unique sonic signal which is compared to digitally stored sonic fingerprints at a given sporting event to identify a match, and starts or stops the game clock in response to that match. This prevents inadvertent game clock starts and stops resulting from ambient noise. The sonic generator can be configured as a two-way voice communication system to allow referees to communicate with other game officials.

A timer for a surgical imaging device is disclosed. The timer determines a working time of an imaging agent and outputs an indicator for display based on the working time. The working time can be a start time at which a signal from the agent is observable at an imaging site and/or an end time at which the agent is cleared.

A method and system for controlling a commercial transaction is presented. An article of manufacture has a time cell that is read by an electronic apparatus. In response to a determination of a state of the time cell by the electronic apparatus, usage of the article of manufacture in a commercial transaction is enabled or denied based on the determined state of the time cell. The expiration period of a time cell controls the time period during which the commercial transaction is enabled or is denied to be performed; an unexpired time cell may both enable or deny performance of a commercial transaction, and an expired time cell may also both enable or deny performance of a commercial transaction. The time cell may be used to restrict the usage period of a coupon, a promotional offer, a pre-paid service, or some other commercial transaction that involves an article of manufacture.

A method for simultaneously timing multiple entities uses a timekeeping device. During timing, each of the multiple entities runs through a process starting with a start time event in a start phase followed by at least one subsequent time event in a run phase. The method comprises the following steps. In the start phase, when a first start time event occurs, a first actuator is manually actuated and the manual actuation triggers the measuring and recording of a first start time by a time measuring means. In the run phase following the start phase, when a subsequent time event occurs, the first actuator is manually actuated and the manual actuation triggers the measuring and recording of a subsequent time by the time measuring means. The timekeeping device also includes an assignment means and a second actuator.

A first measurement point is received from a first monitoring agent. The first measurement point includes a first timestamp and a first transaction attribute. The first timestamp is stored. A second measurement point is received from a second monitoring agent. The second measurement point includes a second timestamp and a second transaction attribute. The second timestamp is stored.

The present invention relates to a time indicator, and more specifically to a time indicator which can indicate times in a multiple manner, thereby enabling a user to be aware of both an effective period and a period having elapsed after the effective period and to rapidly check whether the time indicator is operating.

An dynamic electronic communication device. The tag according to embodiments of the invention is designed or set to discount, promote, incentivize, or apply information at certain states or within a certain timeframe at initial deployment, the tags themselves being capable of handling the logic. The tag generally includes a circuit, such as a silicon chip, that controls a flexible printed display, which displays the information when applied. The tag is optionally encapsulated in a plastic or glass case. The tag is made of a suitably small size such that the tag can easily be placed on individual items, and can be secured to other objects via an adhesive backing, sewn in, pinned on, and the like.

A secure electronic entity, adapted to store at least one object, includes a unit for measuring the passage of time as from a reference date associated with the object. It includes a unit for storing a life span assigned to the object co-operating with the time measuring unit so as to compare the time elapsed and the life span. It further includes an updating and invalidating unit, to update the object life span or to temporarily or permanently disable the object if the comparison shows that the time elapsed exceeds the life span. The invention is in particular applicable to smart cards.
