Abstract: There is provided herein a sensor/monitor combination designed to reduce the risk of pressure ulcer occurrence in immobile patients, wherein the level of patient activity is tracked to determine whether or not that patient has exhibited sufficient activity to merit eliminating a scheduled assisted relocation to a new position. The instant device senses the time since a patient last relocated into a different sitting or lying position. If the patient has not moved during some predetermined time period, the nursing staff will be notified by the invention that it is time to manually reposition the patient. If the patient has significantly changed position during the predetermined time period and, thus, allowed previously compressed tissues to reoxygenate, the invention will not signal that a move is necessary, thereby eliminating the need in some cases to rouse the patient from an otherwise healing sleep.

Abstract: The invention relates to a portable, electronic device such as a mobile phone. The device is provided with a transponder and may be used for authentication purposes. The device includes means for writing user-specific information into a memory unit, included in the transponder. Thus, when an interrogating reading device stimulates the transponder, the transponder emits the user-specific information. This enables authentication of a user rather than of a device. In a preferred embodiment use is made of a user-specific key, by means of which a single-use code is generated, which is used as the emitted user-specific information. The invention also relates to a method and a system, which may work in connection with such a device.
