摘要:
One or more switches may be coupled to a radio frequency identification (RFID) tag, so that the response of the RFID tag indicates the state of the switch(es). The RFID tag and the switch(es) may be coupled together in various ways so that the state of the switches affects the response of the RFID tag to an RFID reader.
摘要:
Low frequency harmonics detected by an accelerometer in a wrist-mounted device are used to infer ambulation. The fundamental rhythm or pitch is extracted from gathered accelerometer data and the determined pitch and associated properties are used to infer whether a subject is walking or not walking.
摘要:
Various embodiments or the invention may use changes in the quantity of responses received from an RFID-tagged object to derive parameters that indicate probably movement or the object. In some embodiments, multiple RFID tags and/or multiple RFID readers may be used in conjunction with one another to further refine the probability of movement and/or to indicate the probability of a particular type of movement.

One or more inertially controlled switches may be coupled to a radio frequency identification (RFID) tag, so that the response of the RFID tag indicates the state of the switch(es). The RFID tag and the switch(es) may be coupled together in various ways so that the state of the switches affects the response of the RFID tag to an RFID reader.
摘要:
User self-installation of a sensor network for activity monitoring may be facilitated by providing a computer system that prompts the user through the installation process. Particularly, the computer system may prompt the user to identify an object to which a sensor has been attached and the activities with which identified objects are associated. The computer may prompt with potential activities based on the object identified by the user. The elicited information may be used to automatically generate a model, which may be automatically improved over time by examining the history of sensor readings. Thereafter, based on the data produced by the sensors, the system identifies what activities are actually being completed.
摘要:
Selective dynamic compilation of source code is performed using run-time information. A system is disclosed that implements a declarative, annotation based dynamic compilation of the source code, employing a partial evaluation, binding-time analysis (BTA), and including program-point-specific polyvariant division and specialization and dynamic versions of traditional global and peephole optimizations. The system allows programmers to declaratively specify policies that govern the aggressiveness of specialization and caching, providing fine control over the dynamic compilation process. The policies include directions for controlling specialization at promotion points and merge points, and further define caching policies, and speculative-specialization policies. The system also enables programmers to specialize programs across arbitrary edges, both at traditional locations, such as procedure boundaries, but also within procedures. Programmers are enabled to conditionally specialize programs based on evaluation of arbitrary compile-time and run-time conditions.
