Apparatus and method for accessing events, areas and activities

Abstract: An access control system and method is provided for an activities center wherein activities are available for customers. The control system employs a plurality of access cards, a comptroller processor, at least one credit station and a plurality of access stations. Each access card is encoded for a respective customer, and the comptroller processes data, creates customer account files correlated to each customer's account file identifier, stores the customer account files, verifies customer account files to determine availability of credit and issues either approval or disapproval. The credit station reads an account file identifiers on an access cards and signals the processor to open the customer account file. An access station is associated with each activity and reads an access card to signal the comptroller processor to open the customer account file. Debit circuitry within each access station generates a debt signal corresponding to a selected cost debt for the respective activity, and the comptroller processor then generates approval or disapproval depending on the customer account credit for that activity. The access station has receiving circuitry responsive to the approval or disapproval signals from the comptroller processor to grant or deny customer access to the selected activity. A plurality of types of credit are used, and the comptroller processor maintains corresponding subaccounts, and the customers may allocate payment at the credit station among the types of credit available.

Technical Errors During Medial Patellofemoral Ligament Reconstruction Could Overload Medial Patellofemoral Cartilage A Computational Analysis

Abstract: BackgroundThe influence of reconstruction of the medial patellofemoral ligament on the patellofemoral force and pressure distributions has not yet been investigated.HypothesisTechnical errors can cause tension to develop within a reconstructed medial patellofemoral ligament, which will adversely alter the normal patellofemoral force distribution by increasing the load applied to the medial cartilage.Study DesignControlled laboratory study.MethodsFour computational knee models were used to simulate knee function from 30° to 90° of flexion with (1) an intact medial patellofemoral ligament, (2) an anatomically correct reconstruction using a double hamstring tendon autograft, (3) a 5-mm proximally malpositioned femoral attachment site, (4) a graft that is 3 mm shorter than the intact medial patellofemoral ligament, and (5) combined proximal malpositioning and a short graft.ResultsThe results were similar for the intact and anatomically reconstructed medial patellofemoral ligament. Proximal malpositioning of t...

Instructional communication in the televised classroom: The effects of system design and teacher immediacy on student learning and satisfaction

Abstract: The present study was designed to investigate the effects of conveyance system design and social presence, in the form of teacher immediacy behavior, on perceived student learning and satisfaction in the televised classroom. Results indicate that system design and teacher immediacy behavior strongly impact student learning and satisfaction. System variables such as interactivity and clear audio and video transmission positively influenced perceived learning and satisfaction. Further, instructors who engaged in immediate behaviors such as encouraging involvement, offering individual feedback, maintaining relaxed body posture and using vocal variety were viewed more favorably.

GPS tracking system

Abstract: A low cost tracking system employing satellites of the global positioning system (GPS) is suitable for applications involving radiosondes, sonobuoys, and other objects. The tracking system includes a sensor mounted on each object which digitally samples the GPS satellite signals and records them in a data buffer. The digital samples are then transmitted, at a rate lower than that at which the GPS satellite signals were sampled, over a data telemetry link, interleaved with other telemetry data from the object. The GPS data is processed in a data processing workstation where the position and velocity of the sensor, at the time the data was sampled, is computed. The data buffer in the sensor is periodically refreshed, and the workstation periodically computes the new position and velocity of the sensor. Differential corrections are also provided at the workstation to aid in signal acquisition and to increase the precision of the position fix.
