A health club exercise records system in which members to the health club are given a handheld device that is pre-programmed by the trainer or health club operator to record different exercise activities. The handheld device includes a built-in numeric keypad, a display monitor, and optical reader designed to communicate with a compatible ID tag located on or in the vicinity of the exercise activity data source. Loaded into the working memory of the handheld device is a pre-programmed exercise data collection program. The exercise data collection program displays one or more sub-routines to the member requesting the member to input information regarding the exercise. The sub-routines are specific to the exercise activity data source and present one or more prompts requiring the member to input information. The inputted information is stored in a temporary data file located on the handheld device or transmitted immediately to a permanent member data file on a local server located in the health club. The system may also include an uplink terminal for transmitting the data in the temporarily data file to a remote server connected to a network operations center. A fitness tools software program is loaded into the server for collecting and processing the data in the member's permanent data file which may be reviewed by the trainer and/or member.

In an access controller provided for a musical sound signal generating system, a signal generating section operates when a readout of wave data of one block stored in a working memory is completed in a sound channel, for supplying a next waveform request signal to a CPU, which requests a next block of the wave data for the sound channel. First and second buffer memories are connected between a recording medium and the working memory respectively through first and second buses which are independent from each other. A first transmitting section operates when receiving block specifying information from the CPU, which specifies a block to be read next from the recording medium, for transmitting the wave data of the specified block to either of the first or second buffer memory while reading the specified block of the wave data from the recording medium. A second transmitting section operates when the transmitting of the wave data to either of the first or second buffer memory is finished and during a period when the musical sound signal generation system is not accessing the working memory, for transmitting the wave data of the specified block to the working memory from either of the first or second buffer memory, to which the wave data of the specified block has been transmitted by the first transmitting section.

The invention relates to the technical field of brain function network research and more particularly relates to a brain function network construction method based on a micro-state. Starting from theconstruction of an EEG brain function network, according to the theory of EEG micro-state related aspects, namely that the EEG micro-state is the most basic state which reflects the brain activity, proposing that the EEG micro-state can also be applied to construction of the brain function network. The method provided by the invention solves the problem that the time consumed for construction of the traditional brain function network is too long and reduces a large quantity of redundant information in an original EEG time sequence by using the time sequence after micro-state reconstruction. Byapplying the method to an EEG data set of mental disease working memory collected in a hospital, the EEG brain function network for schizophrenia patients and normal persons is constructed; and compared with the brain function network constructed by using an original EEG signal, the brain function network constructed by the time sequence after micro-state reconstruction has the advantage that thecharacteristics of the human brain network can be more accurately reflected.

An arterially measured pressure signal is continuously read in and temporarily stored in the working memory (RAM). The function p(t) is processed by the central processing unit (CPU), to calculate the heart/time volume PCCO and other hemodynamic parameters. The calculation comprises the following steps: The systemic vascular resistance SVR_k is calculated for the current pulse period. The stroke volume SV_k is numerically determined from the pressure values of a pulse period, according to the following equation: ${\mathrm{SV}}_k\propto \sum \left(\frac{p_i\left(t\right)}{{\mathrm{SVR}}_k}+C_k\left(p_i\right)\frac{d{p}_i}{dt}\right)$

with the compliance C(p)=(MAP−CVP)_k/[SVR·<dp/dt>_k]·f(p). The difference between the mean arterial pressure MAP and the central venous pressure CVP, and the mean incline of the pressure curve in the diastole <dp/dt>, are re-determined for the current pulse period. The heart/time volume calculated in the current pulse period results from PCCO_k=SV_k·HR. Therefore, continuous recalibration of the systemic vascular resistance and of the compliance takes place, from the continuously determined pressure measurement data.

The extent of the patient's ADHD related symptoms and the severity of the disorder may also be assessed. Additionally, patients who are affected by ADHD may be administered medications intended to address their symptoms and based on comparing the severity of the patient's symptoms on and off therapy, the efficiency of the medication may be gauged and a measure may be provided of how well individual patients respond to a given medication.

Systems and methods for managing records stored in a storage cache are provided. A cache index is created and maintained to track where records are stored in buckets in the storage cache. The cache index maps the memory locations of the cached records to the buckets in the cache storage and can be quickly traversed by a metadata manager to determine whether a requested record can be retrieved from the cache storage. Bucket addresses stored in the cache index include a generation number of the bucket that is used to determine whether the cached record is stale. The generation number allows a bucket manager to evict buckets in the cache without having to update the bucket addresses stored in the cache index. In an alternative embodiment, non-contiguous portions of computing system working memory are used to cache data instead of a dedicated storage cache.
