Abstract: A digital logic module of oximeter sensor probe includes a detection probe, an operation circuit, and an integrated circuit. This digital logic module of oximeter sensor probe is provided with the light source driving function and the light source capturing function for reducing loading of the microprocessor, so that a cheaper microprocessor can be used in the oximeter sensor for reducing the development cost of the oximeter.

Abstract: A refrigerator is disclosed. The refrigerator with a body fat meter calculates a body fat rate according to an impedance of a human body when the user touches both of the body fat detecting buttons, displays the body fat rate on a screen, and keeps a historical record of the detected body fat rate. According to the historical record of the detected body fat rate, the user may be aware of the increase of the body fat rate.

Abstract: A patient monitor apparatus coupled to LAN of a hospital is provided. The apparatus comprises a body signal reading module for obtaining at least one body signal, a signal processing module for digitally processing the body signal to obtain at least one record of body data prior to converting into at least one Web page, and a monitor module for showing data, and a network interface interconnected the signal processing module and the LAN for sending the Web page to any computer over the LAN. A medical staff (e.g., nurse or doctor) whether locally or remotely located, can immediately know the conditions of a patient by typing a unique address of the apparatus on a computer by viewing the Web pages of the patient.
