Description:
TECHNICAL FIELD 
       [0001]    The description relates generally to a capsule that is adapted to be ingested by a human for collecting calorie intake data. 
       BACKGROUND 
       [0002]    People starts to pay more attention to their health. There are many contributing reasons to a person&#39;s health. Eating habit is one, if not the most, important reason to one&#39;s health. There are many books and software teaching people what to eat, how to eat. There are also many systems tracking what people eat. However, everyone is different and their digestion system is different. The same food may lead to different result on different people. This calorie measuring capsule gathers data from within the user&#39;s digestion system. By tracking this data, combining with other user-specific data, such as exercise activity, heart rate, sleeping time etc, it allows a more personal analysis on what kind of food is good for that person and what kind of life style is to be suggested. 
         [0003]    The capsule can send measured data in real time wirelessly to be received and calculated by a receiver. The capsule can also have a microprocessor and a data storage device so that the data is stored and can be retrieved later in a monitored environment. 
       SUMMARY 
       [0004]    In accordance with a first aspect of the present invention there is provided a capsule adapted to be ingestable by a human and comprising a calorie measuring device for determining the calorie intake of the human. 
         [0005]    In a preferred embodiment of the invention, the calorie measuring device comprises a density sensor, a weight sensor and a sugar level sensor. 
         [0006]    In a further preferred embodiment, the capsule comprises a wireless data transmitting device. This allows measured data be sent in realtime through wireless signal. 
         [0007]    In a further preferred embodiment, the capsule comprises a microprocessor and data storage device to process measured data, calculate calorie intake and store related data in the data storage device. This allows any data collected by the capsule to be extracted when the capsule is ejected. 
         [0008]    Other features and advantages of the invention will become apparent to those skilled in the art upon review of the following detailed description, claims and drawings.

     DETAILED DESCRIPTION 
       [0014]    In  FIG. 1 , a capsule  1  has inlet and outlet holes on either end of the capsule. These holes allow fluid to flow into the capsule to be sampled by sensors. The capsule  1  is made of medical-grade polycarbonate, or any other suitable material, and is between approximately 16 mm and 41 mm long and between 6 mm and 16 mm in diameter. 
         [0015]    In  FIG. 2 , the horizontal section of the capsule is divided into five sections. Bottom section  1  is filled with high-density materials to ensure the capsule lays flat with the bottom section on the bottom. Density sensor section  2  houses density sensor. The density sensor measures the weight on the surface  2   a  G 2   a . Sample section  3  is for liquid to flow through. The volume of section  3  is fixed per capsule V 3 . The density of the liquid can be calculated as D=G 2   a /V 3 . Calorie sensor section  4  houses glucose sensor. The glucose sensor measures sugar level in the liquid through surface  4   a . C 4 . Calorie index CI is calculated as: CI=C 4 ×D×4. Weight sensor section  5  houses weight sensor. 
         [0016]    The weight sensor measures weight on the outside surface of the capsule  1  G 5 . The calorie index CI and the weight G 5  are both sent to receiver to be tracked. 
         [0017]    In  FIG. 3 , the vertical section of the capsule is divided into seven sections. Sections  1 - 5  are described above. The transmitter section  6  houses a microprocessor  8  and a wireless transmitter  9 . The microprocessor  8  converts sensor data into digital data and the transmitter  9  transmits data wirelessly to be received by a receiver. The microprocessor  8  is a AD7817 processor, although any suitable processor could be used as an alternative. The storage section  7  hoses a data storage device. The microprocessor sends converted sensor data to the storage device. 
         [0018]      FIG. 4  shows a circuit diagram for the capsule. The density sensor, glucose sensor, weight sensor, wireless transmitter and data storage devices are all connected to the microprocessor  8 . 
         [0019]      FIG. 5  shows the steps that are followed when the capsule collects data and sends data.
