Disclosed is a visual timer, comprising a back shell, a PCB board, an encoder, a color display screen, an adjusting knob, a knob sleeve and a lens. The PCB board is arranged on the front of the back shell, the encoder is arranged at the bottom of the front of the PCB board, the color display screen is arranged on the front of the PCB board, the adjusting knob is arranged on the front of the encoder, the knob sleeve is arranged on the front of the adjusting knob, and the lens is arranged on the front of the color display screen. The timer provided by the invention has the characteristics of time visualization, low efficacy and convenient time adjustment by the adjusting knob, and the maximum timing range can be switched to 120 minutes and 60 minutes.

A power control system may include an uninterruptible power supply (UPS), a display device, load measurement circuitry to determine a load percentage of the UPS, and a controller. The controller may receive the load percentage of the UPS from the load measurement circuitry; monitor the load percentage of the UPS to determine whether the UPS is operating in a nominal load state or an overload state; generate an input overload countdown timer when the UPS is operating in the overload state, where the input overload countdown timer provides an estimated time remaining in the overload state; generate an output overload countdown timer by applying a minimum envelope filter to the input overload countdown timer; and direct the display device to display the output overload countdown timer. Additionally, the minimum envelope filter may be operated in an open-loop or a closed-loop configuration.

Timing systems configured to be used with a computing device including an electronic display and a tilt sensor. The timing systems include a switch and computer executable instructions. The switch includes a base and a cradle. The cradle is pivotally mounted to the base and configured to support the computing device. The cradle is configured to pivot relative to the base between a first pivot position and a second pivot position. The computer executable instructions are stored on the computing device and include instructions for displaying a game timer on the electronic display of the computing device. The instructions include controlling the game timer in response to the tilt sensor detecting that the cradle has pivoted between the first pivot position and the second pivot position.

This present invention relates to a dental care timer that informs both children and adults to brush their teeth for a minimum period of time, preferably two minutes. The dental care timer is preferably comprised of a stylish housing with a mounting or supporting structure. The front of the housing features a display for a countdown timer, a power button, and a speaker. An internal battery powers the dental care timer and its various components, and the timer device is capable of communicating with a user's smart device, such as a smart phone, smart watch, tablet or the like. Upon the conclusion of an appropriate brushing session, the dental care timer will emit an audible signal to the user.

A handheld pool game clock apparatus suited for timekeeping pool/billiard games is presented. The handheld pool game clock apparatus contains a clock body, at least one display, a processing unit, at least one switch, and a control panel. The at least one display is distributed around the clock body. The processing unit and the at least one switch are connected within the clock body. The control panel is connected adjacent to the clock body. The at least one display, the control panel, and the at least one switch are electronically connected to the processing unit.

A detonator for use in a detonating system, which detonator includes discriminating and validating arrangements which sense and validate at least one characteristic of at least one parameter produced by at least one of a light, acoustic, vibratory, magnetic or electrical signal event, and an electronic timer which executes a timing interval in response thereto.

In one embodiment there is a method for activating a function of a mobile application on a mobile device, using a movable device, the movable device including a processor, the processor including an inertial measurement unit and a wireless transmitter. The method comprising: at the movable device: detecting a movement signal at the inertial measurement unit indicating movement of the movable device; in response to detecting the movement signal from the wireless transmitter, determining whether the movement signal meets movement criteria; in response to determining that the movement signal meets movement criteria, transmitting a function activation signal to the mobile device to activate the function of the mobile application; and in response to determining that the movement signal does not meet movement criteria, refraining from transmitting a function activation signal to the mobile device to activate the function of the mobile application.

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.
