System and method for acquiring data

A system for acquiring, and displaying, data such as physiological data, from a plurality of data connection devices, each of which monitor one or more different parameters and output data at different sampling frequencies based on their own system clocks. The system receives the data signals at different sampling frequencies and associates each sample of each signal with a time stamp derived from a single master clock. Low rate and high rate data are treated differently. Low rate data is associated with the current value of the master clock, where as high rate data is time stamped by giving the first sample a time stamp equal to the current value of the current master clock, subsequent samples being given an estimated time stamp based on the expected interval between samples derived from the sampling frequency of the data collection device, and the timescale given to the first example. The estimated time stamp may be periodically corrected, and the estimation calculation can be improved by correcting the value used for the interval between samples. The different signals can be displayed together on a display aligned with respect to a time axis. The system can display, the data in two different timescales, one showing a few seconds of data and one showing a few hours of data. The data traces are scrolled across the time axis, new data being added to one end of the trace.

Device communications of an implantable medical device and an external system

An implantable medical device, external unit, and method for establishing communication between them are disclosed. The external unit learns the frequencies of transmission and reception for the implant. The transmit frequency of the implant is learned by the external unit measuring a difference between the transmit frequency of the implant and the external unit's receive frequency.

Mobile fitness and personal caloric management system

A user's personal biometric information such as age, sex, weight, height as well as the user's lifestyle information, such as daily caloric input, job description, smoker status and physical fitness, is uploaded onto a host computer. Target heart rate, energy and / or caloric consumption levels related to desired fitness and weight loss goals for a particular individual are then selected having regard to fitness levels for an individual of comparable age, and consuming similar calories are then downloaded to a caloric monitoring unit. The caloric monitoring unit is provided for measuring the user's heart rate and dynamic energy and / or caloric expenditure over one to four weeks. The caloric monitoring unit includes a heart rate monitor, a unit accelerometer, a global positioning system (GPS), and an audio and / or video output. The audio / video output is operable to provide information and / or motivational prompts to the user in the event the heart rate, energy expenditure and / or caloric expenditure falls below or exceeds pre-selected target expenditures over a particular time segment of the selected time period having regard to the calories which are consumed. A display provides a continuously updated visual indication of whether or not the use has achieved the pre-selected optimum caloric burn or energy expenditure for that particular time segment. An internal calendar / clock, a processor and / or memory in the caloric monitoring unit compares measured heart rate and energy expenditures for multiple time segments against target levels stored as the user-specific fitness programme tailored to achieve the desired weight loss. The comparison is then used to generate compliance output data to either the user and / or a nutritionist.

Error code calculations for data stored in an implantable medical device

A cyclic redundancy code (CRC) and optionally a syndrome value calculation of one or more implantable medical device (IMD) data block is conducted by block mover / reader hardware of the IMD when the data block(s) are moved and / or read. In the block read operation, each data byte or word in the block mover data register is read in a first clock cycle. In the block move operation, each data byte is read in the first clock cycle in this way and then moved to a destination register in a second clock cycle. The data CRC and optionally the syndrome value accumulate in the CRC and syndrome registers as all data bytes of the data block(s) are read in the first clock cycle. When the last data byte or word of the data block(s) is sequentially read (and moved in the block move operation), the accumulated data CRC and syndrome value are either stored as the associated data CRC and optional syndrome value or are used for comparison with a previously stored data CRC and optional syndrome value associated with the data block(s) in the comparison operation to determine if the data block(s) is corrupted.

Pharmaceutical Dosing Method

Systems, devices, and methods for more accurately determining a radiopharmaceutical dose administered to a patient by relying on a time factor. Particularly, broadly contemplated herein is the administration of a dose on the basis of an elapsed time from when a dose was last accurately measured in the past to when it is injected into the patient. As such, when a dose is first measured, that timepoint is preferably recorded whereupon the time of injection or administration into a patient is also recorded. Based on the original measured dose, the radionuclide (and thus its known decay rate) and the time elapsed, the dose is calculated and not directly measured on injection. The clocks on the filling station and the transport cart are synchronized to each other or to a known and accepted time standard. In this manner, there is temporal continuity and no inaccuracies of time or loss of time occurs between measurement and injection.

Systems and methods for managing discussion threads based on ratings

System and method for removing threads from discussion groups based on ratings of the individual posts within the thread. If a user takes the time to rate a post positively, then the post (and the thread) is considered to be useful to the entire community and should not be deleted. To rate the post, a window is displayed to the user whenever the post is open and queries the user whether the post is useful. A positive rating resets a delete date associated with the post. If there is not positive rating of a post, the thread may be considered useful if the originator of a post marks the post as being answered, in which case delete clock is reset. If however, none of the posts within the thread are rated positively, then the thread is considered not be useful and deleted.

When irradiated upon animals during their customary sleeping hours, or when they are sleepy, or have been sleeping, Anti-Carcinogenic™ night light does not disrupt the hormonal secretions of the pineal gland. Conventional light, associated with pollution of the sky and urban areas, disrupts hormonal secretions, and much evidence points to hormonal secretion disruptions as a cause of cancer. The novel Night Lights can illuminate areas adjacent bedrooms, dormitories, and in vehicles, buses, aircraft, where passengers customarily sleep, and in refrigerators, and on illuminated clocks and watches. These Night Lights can have back-up power supply and employ motion sensors and photoelectric switches to switch on Anti-Carcinogenic™ (non-carcinogenic) illumination when needed for safe movement in otherwise darkened areas, and can detect power failures, noises indicative of violence, such as panics, school shootings, cries for help in medical emergencies, or assaults, and also detect dangerous, toxic, or explosive substances, including particulates, bacteria, viruses, thereupon they communicate alarms by sound, optical cable, laser, or radio frequency.
