A chair-based scale for weighing a person in a seated position is disclosed. The scale includes a system for electronically displaying data and other information. In one embodiment, the chair-based scale is a stand-alone scale, and in other embodiments, it communicates with a remote computer. According to one embodiment, the chair comprises a collapsible chair. A collapsible chair provides certain advantages, such as lower manufacturing and shipping costs, and ease of shipping to and storage and use at a user location (e.g., a patient's home or apartments), or a health care facility. According to an embodiment of the invention, the collapsible chair may be a folding chair, e.g., of the deck chair or director chair type. According to one embodiment, the chair comprises a protective cover that is movable to prevent loading of a load sensor in a non-weighing condition of the chair. In another embodiment, the chair is provided with wheels and e.g., is of the transport type.

The monitoring device(s) includes at least one physiologic sensor for measuring at least one physiologic parameter of a subject and a wireless communication unit. The transmission device includes at least one communication unit for communicating with the monitoring device wirelessly and for communicating with a remote computer. The monitoring device(s) communicate data measured with the monitoring device to the transmission device wirelessly and the transmission device communicates the measured data to the remote computer.
摘要:
A global navigation satellite system (GNSS) receiver may be operable to quantize two-dimensional GNSS sample data with an in-phase (I) and quadrature (Q) pair to two-dimensional quantized data with a magnitude and angle pair using the polar quantization, for example, an unrestricted polar quantization. The GNSS receiver may be operable to reduce a size of the two-dimensional quantized data for storage by representing the two-dimensional quantized data by the one-dimensional symbol data. The one-dimensional symbol data may be stored in a random access memory (RAM) for further processing. The I and Q pair associated with the one-dimensional symbol data stored in the RAM may be retrieved and processed by the GNSS receiver using a correlation such as a fast Fourier transform (FFT) correlation.
