Abstract: A method for deriving an independent current time estimate from celestial sources comprising: providing a reference measurement for a variable-intensity celestial source, wherein the reference measurement comprises the celestial source's photometric structure at a known time, at a known stellar period, and at a known periodic phase; creating a phase-folded light curve for the celestial source; measuring an intensity of the celestial source at a subsequent time; comparing the measured intensity of the celestial source to the phase-folded light curve to derive a set of possible phase differences, wherein each possible phase difference corresponds to a potential derived time based on the known time and the known stellar period of the reference measurement; and analyzing the set of possible phase differences to derive the current astrophysical time.

Abstract: Ultra-short pulse detection. At least some example embodiments are methods including: receiving by an antenna a series of ultra-short pulses of electromagnetic energy at a repetition frequency, the receiving creates a pulse signal; self-mixing or intermodulating the pulse signal by applying the pulse signal to a non-linear electrical device, thereby creating a modulated signal; and filtering the modulated signal to recover a filtered signal having an intermodulated frequency being the repetition frequency.

Abstract: A time validation indicator is disclosed comprising at least a receiving layer and an activating layer. The receiving layer comprises at least one or more masking colorants and one or more deactivators that cause and maintain the one or more masking colorants in an initial colored state. The activating layer comprises at least one or more migratory activators that migrate into the receiving layer upon at least a portion of the receiving layer being placed in contact with at least a portion of the activating layer to initiate a predetermined time period. The migration of the one or more migratory activators into the receiving layer causes at least a portion of the one or more masking colorants to advance to a final colorless state resulting in a visual color change of the receiving layer that indicates the predetermined time period has elapsed. Also disclosed are methods for creating and using the inventive time validation indicator.

Abstract: A system for recording and displaying a time-sequential scene on a computer comprising a digital camera, an image timer, and a main control computer. The digital camera transmits a sequence of digital image frames to the timer representative of the image of a body passing a plane in space. Each frame represents a line of the body, thus forming a fractional part of the scene. Once the frame reaches the image timer, it is digitally marked with a time reference and buffered into a block of information. The main control computer stores blocks of information from the image timer for a variety of processing and features available to the user. A compression system compresses a sequence of digital image frames for storage into a selected memory, preferably a virtual memory subsystem, or hard-disc drive.

Abstract: A photographing mechanism for a moving body camera, namely a slit camera, utilized for judgement of arrival order in horse race, etc. A light array 18 consisting of vertically arrayed plural LEDs is located closed to film 4. A light emission control box 17 illuminates and unilluminates the LEDs in response to dot data of characters to be recorded. Hence, as the film 4 is rewound, the film 4 is exposed by the LEDs, so that the characters are recorded on the film.

Abstract: Method and apparatus for measuring the time of short events, such as characteristics of a source of short radiation pulses or lifetime of excited states of a sample. The method and apparatus is based on a multi-step photoemission process from an active element target exhibiting superlinear photoemission. A short prompt radiation pulse is used to raise electrons to an excited state, and a following overlapping short probe pulse is used to raise the excited electrons to the vacuum level where they leave the sample, changing its charge state. The number of escaped electrons is measured as a function of the time delay between the prompt and probe pulses to provide the sought after information. Preferably, the charged target is suspended or supported in an electric field, and the voltage needed to restore the charge-changed target to its original position is used.

Abstract: Image signals of moving subjects which are imaged by a slit camera, and time information generated by a time information generator after it has been reset by a start trigger signal, are successively stored in and erased from a large-storage-capacity memory on a first-in, first-out basis. After elapse of a predetermined time period after a record trigger signal has been supplied from a record trigger generator, a storage time control circuit controls the memory to stop storing and erasing the image signals and the time information, and keeps the image signals and the time information stored which have been stored before the memory stops storing and erasing the image signals and the time information. The image information of the subjects and the time information associated with the image information can be stored in the memory within a storage time that depends on the storage capacity of the memory.
