Abstract:
The present invention relates to a system for diet control; more specifically, to an autonomous portable electronic device, which allows the user easily, input a nutrition facts data about the food he or she takes into the device. The device can extract, display, and store in a cumulative fashion the nutrition facts he or she takes, and possibly give a warning message when the user takes more nutrition facts than their needs, and possibly give a suggestion helping the user to select to meal. Also, the device can easily send the user&#39;s nutrition information to the restaurant/food store when they buy the food so the restaurant/food store can make the food based on the user&#39;s nutrition requirement. Also, the device can count the energy consumed by the user, and give the user a hint on how to adjust his or her nutrition/diet control.

Description:
[0001]    The present invention is based on the provisional Patent Application, Ser. No. 10/716,558, filed on Sep. 14, 2005, titled “Nutrition/diet control system”. 
     
     FIELD OF THE INVENTION 
       [0002]    The present invention relates to a device/system for nutrition or diet control, more specifically, a restaurant or food/grocery store host system, and to an autonomous portable electronic device which easily allows the user to input nutrition facts data and other information about the food he or she takes for their diet watch or nutrition control. 
       BACKGROUND OF THE INVENTION 
       [0003]    A large percentage of the United States adult population is overweight. Many publications are available regarding diet/nutrition control or weight watching, which their readers hope will provide an easy solution to their weight problems. Competent medical specialists who have studied the problems of obesity generally are convinced, however, that the only effective method of controlling weight is to balance the intake of energy in the form of food with the expenditure of energy in the form of activity. Whenever an imbalance exists in the form of a greater energy intake than is expended, an increase in weight results. In theory, the maintenance of a balanced caloric intake/expenditure should be easily established. Readily available charts have been published which provide accurate data on the caloric content of all types of foods and beverages. In addition, caloric expenditures of a wide range of human activities from sleep through strenuous exercise have been measured and charted. Many thousands of individuals have succeeded in achieving their desired weight and maintaining that weight by balancing their caloric intake with expenditure. Therefore, many persons use so-called calorie counters or pedometers for watching their weight. For example, walking burns calories. To figure out how you are doing, here is a simple equation: If you walk at the leisurely pace of 3 miles per hour, you can burn about 300 calories in an hour. 
         [0004]    Controlling one&#39;s nutrition intake is a major focus of health maintenance. Moderation of caloric and fat intake is a common concern for the public. Precise control of elements such as sodium, protein, and fiber are required for segments of the population whose health has been compromised by medically important conditions. 
         [0005]    The FDA was worried that Americans had no way to judge food labels to make healthy food selections. After many months of hearings and debate, it came up with a solution—give all Americans a Nutrition Budget, a Daily Value for fat, saturated fat, cholesterol, sodium, total carbohydrate, and dietary fiber. Consumers would like to be abnormally diligent to add up the % Daily Value for each serving of each food that they eat to make sure they eat less than 100 percent of the Daily Value for each nutrient each day. 
         [0006]    The Daily Value gives us an easy way to watch our nutrition intake. Therefore, there are many designs or proposals that seek to allow the user to input the % Daily Value into to a computer or an electronic device, which will show the user how much the nutrition facts they have taken in the serving. The patent application (U.S. Pat. No. 5,819,735) even suggests using a bar code scanner to help the users to enter the nutrition facts into a device or a computer. U.S. Pat. No. 4,686,624 to Blum uses a database that contains food names, such as semi-skimmed milk, and the related nutrition facts. Sakai, in U.S. Pat. No. 4,855,945 describes a similar device, wherein a nutrition fact database can be accessed by entering actual food names via an alphanumeric keypad. It is not easy for the user to enter the food nutrition data into their portable device, such as a cell phone or PDA, while they are ordering their food. 
         [0007]    Using a scanner to scan the nutrition facts information into the device will add the cost into the device, and also requires the food providers to put the bar code labels on the food box or on the restaurants&#39; menu. Another disadvantage of the prior art is that it cannot show you the relation or the link between the nutrition/energy (calories) you took and the nutrition/energy (calories) you consumed. 
         [0008]    Research shows that people who keep track of what they eat have better weight-loss success. People tracking what they eat will pay more attention about what they eat, will get a better diet result. In hospitals or diet clubs, there are nurses or trainers helping patients or the club members tracking their take nutrition/energy data. The nutrition facts label is now the best and most widely used source for nutrition information. Now, when you buy a package of food from supermarket or a food/grocery store, you can easily find the nutrition information about the food on the nutrition facts label on the package. However, when you eat a meal in a restaurant, such as Burger King or McDonald&#39;s, it is not easy for you to find the nutrition information about the food you ordered. Some restaurants, like McDonald&#39;s, give their customers a well-printed paper listing the nutrition information for all their meals on their menu. Since there is a great deal of nutrition information on this paper, few customers will take the time to look at the paper and count out how many fats or calories he or she is taking, especially when an extra side comes with the meal they ordered. Also, some people will be allergic to a certain ingredients in the food, such as eggs. Usually, many new employees in a restaurant or a food store don&#39;t have much knowledge about the ingredients in the foods they provide. In some cases, such as in a hospital or a diet club, or even a health insurance company, the doctors or the diet instructors want to keep track of the nutrition, such as fats and calories, that their patients or clients have taken, and the nutrition/calories they have consumed. However, the prior art technology didn&#39;t provide a good solution or answer to these issues.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0072]    Referring now to the drawings,  FIG. 1  shows an ordering or cashier system with nutrition control in accordance with the present invention. In this example,  100  is an ordering or cashier machine in a restaurant/food store/grocery store, which includes  101  processor,  102  storage/memory,  103  display device,  104  printing device,  105  key board or the other type input device, and  110  data bus. Storage/Memory  102   a  is used for storing the information about the food and its price, which is common to the regular casher machine. Storage/Memory  102   b  is for storing the information about the food and its nutrition facts data. When a customer makes an order, for example, he wants a Hamburger, a Coke and Fries, after the cashier/the clerk inputs the customer&#39;s order into the cashier machine  100  through the input device  105 , the processor  101  will look up the price for each items in the order from the storage/memory  102   a , and sum up the total price for this order. The processor  101  will also look up the nutrition facts data for each items or sub-items in the order from the storage/memory  102   b , and sum up the total nutrition facts for each individual order/meal in the order. The system will print the customer&#39;s order ticket or the order receipt in a small slip/piece of paper, which shows the customer order with the food item name, the price, and also the nutrition information for each individual order/meal. The system may also display the nutrition data for the customer order on the display device  103  when processing the order. 
         [0073]      FIG. 2A  shows a regular restaurant/food store/grocery store order ticket or receipt. In this order ticket, there are three individual orders or meals: an Angus Steak Burger, a Spicy Tender Crispy Chicken, and a Kids Meal. The individual order or meal of the Angus Steak Burger includes three sub-items: the Angus Steak Burger, French Fries, and a medium sized Coke. The individual order or meal of the Spicy Tender Crispy Chicken includes three sub-items: the Spicy Tender Crispy Chicken, French Fries, and a medium sized Coke. The Kids Meal includes four pieces of Chicken Tenders, small French Fires, and a Kids Soda. The individual order or meal of the Angus Steak Burger costs $4.99. The individual order or meal of the Spicy Tender Crispy Chicken costs $5.29. The Kids Meal costs $3.19. 
         [0074]      FIG. 2B  shows the restaurant/food store order ticket or receipt in accordance with the present invention. In this order ticket, there are three individual orders/meals, an Angus Steak Burger, a Spicy Tender Crispy Chicken, and a Kids Meal. The individual order or meal of the Angus Steak Burger includes three sub-items: the Angus Steak Burger, French Fries, and a medium sized Coke. The individual order or meal of the Spicy Tender Crispy Chicken includes three sub-items: the Spicy Tender Crispy Chicken, French Fries, and a medium sized Coke. The Kids Meal includes four pieces of Chicken Tenders, small French Fires, and a Kids Soda. The individual order or meal of the Angus Steak Burger costs $4.99. The individual order or meal of the Spicy Tender Crispy Chicken costs $5.29. The Kids Meal costs $3.19. According to the present invention, the nutrition information/nutrition facts for each individual order or meal will be shown on the receipt. In this example, the nutrition information or nutrition facts are displayed in the order of Nutrition Facts Order: Calories/Fat/Cholesterol/Carbohydrate/Protein. In this example, it shows three different formats for displaying the nutrition information/facts. For the individual order or meal of Angus Steak Burger, the nutrition information/facts are displayed in (68%72%20%24%56%). It means that the individual order or meal of the Angus Steak Burger contains 68% daily value of Calories, 72% daily value of Fat, 20% daily value of Cholesterol, and 56% daily value Protein. For the individual order or meal of the Spicy Tender Crispy Chicken, the nutrition information/facts are displayed in &lt;810/47/60/72/28&gt;. It means that the order of Tender Crispy Chicken contains 810 Calories, 47 g Fat, 60 mg Cholesterol, 72 g Carbohydrate, and 28 g Protein. For the Kids meal, it shows [500/30/40/30/20]. It means that the kids meal contains 500 Calories, 30 g Fat, 40 mg Cholesterol, 30 g Carbohydrate, and 20 g Protein. This is just an example of the order ticket/receipt. They may be in a different format. The customer can keep the order ticket or the receipt for tracking the nutrition/energy they took. He or she may enter their nutrition data into their nutrition control device later. It will help the user to keep track of the nutrition/energy they taken. 
         [0075]    According to the present invention, the nutrition information/facts for each sub-item is stored in the above-mentioned cashier machine  100 . Therefore, the nutrition information/facts can be displayed for each different order choice. For example, one customer orders a Hamburger with a large-size French Fries and a large Coke. The cashier machine  100  will look up the nutrition information in the storage/memory  102   b , and sum up the total nutrition facts for each order, and will print the nutrition facts information in a certain format on the receipt or order ticket. The customer will enter the nutrition facts to their own weight watching or diet control device later based on the data shown on the ticket. 
         [0076]    According to the present invention, in order to save the user&#39;s data entry time, the nutrition facts can be displayed by a shorter alternate codes, such as so called Points methods, or the other encoded math mapping method. 
         [0077]    Therefore, the users/the customers will enter less data into their own weight watch or diet control system. 
         [0078]      FIG. 3  shows another example of the nutrition/diet control system in accordance with the present invention. In this example,  300  is an order taking or a cashier machine in restaurant/food store/grocery store, which includes  301  processor,  302  storage/memory,  303  display device,  304  printing device,  305  key board or the other type input device for the cashier or the clerk entering the data into the order taking system or cashier machine  300 ,  306  customer input device, and  310  data bus. Storage/Memory  302   a  is used for storing the information about the food and its price, which is common to the regular casher machine. Storage/Memory  302   b  is for storing the nutrition information, such as nutrition facts data, for the food or meal, and Storage/Memory  302   c  is for storing the ingredient information and the other information, such as the taste (example: sweet or spicy), for the food or meal. The customer makes an order. For example, he orders a Hamburger, Coke, and Fries. After the cashier inputs the customer&#39;s order into the cashier machine  300  through the input device  305 , the processor  301  will look up the price for each items in the order from the storage/memory  302   a , and sum up the total price for this order. The processor  301  will also look up the nutrition facts data for each items or sub-items in the order from the storage/memory  302   b , and sum up the total nutrition facts for this order. The processor  301  will also look up the ingredient information for each items from storage/memory  302   c , and check whether or not there are ingredients the customer doesn&#39;t want. The system will print the customer&#39;s order ticket or the order receipt in a small slip/piece of paper, which shows the customer order with the food item name, the price, and the nutrition information/summary. The system may also display the nutrition data for the customer order on the display device  303  during the processing of the order. The customers input device  306 , here, allows the customers to input their nutrition information, or ingredient information, or even taste choice into the cashier or the order-taking machine  300 . Upon the customer&#39;s input, the processor  301  will look up the nutrition information or the ingredient information or even the other information such as taste in the storage/memory  302   b  or  302   c , and display the best matches on the display device  303  to help the customer to select their meal. The customer input device  306  can be a simple keyboard/mouse, or a touch screen. The customer input device  306  can also be a barcode reader. In this case, the customer has a small nutrition card with the preprinted barcode for his individual nutrition requirement/preferred choice. He or she simply scans the card and sends his or her nutrition requirements or preferred choice to the cashier or the order-taking machine. The customer input device here can also be a small device with the advanced technology which can read, through the air (wireless) or RFID technology, the information from the customer&#39;s portable device, such as customer&#39;s cell phone/PDA or blackberry handhold device. In this case, the customer can send his required or preferred nutrition information or ingredient information to the customer input device  306  in the cashier/order-taking machine  300 . For example, his preferred nutrition requirement for the lunch is 500 Calories. The processor  301  will look up the storage/memory  302   b , and find the matches and show them on the display them for example, Crispy Chicken, on display  303  in the device  300 . 
         [0079]      FIG. 4  shows an example of the nutrition card according to the present invention. In the nutrition card  400 , there is a barcode  401  for the user&#39;s nutrition/ingredient requirements. In this example, the user&#39;s nutrition requirements are:

The employees will know the customer&#39;s requirements, and they can prepare the food based on them. The nutrition card of the present invention can also be used in the hospitals to help the doctors to control the nutrition their patients taken. 
         [0081]    Although the above-mentioned nutrition card is a small card with pre-printed barcode for recording the user&#39;s preferred nutrition requirements, it can be something like smart card, PDA, cell phone, RFID, or the other portable devices. 
         [0082]      FIG. 5  shows another example of the nutrition/diet control system in accordance with the present invention. In this example,  500  is a customer portable device, such as a cell phone, PDA, RFID, or smart card/device, which includes  501  processor,  502  storage/memory,  503  display device,  504  keyboard/pad or other input device,  505  a step counter/pedometer, and  510  data bus. Storage/Memory  502   a  is a regular storage device for storing the information used by the users or the system in the device. Storage/Memory  502   b  is for storing the nutrition information, such as nutrition facts data, for many different kinds foods. Storage/Memory  502   c  is for storing the nutrition information such as fats, calories and protein the user has taken. Storage/Memory  502   c  may also store the table for the standard nutrition need per day, which are suggested by the doctors or the nutrition experts or the government. Storage/Memory  502   d  is for storing the nutrition/energy the user has consumed. Display device  503  is used for displaying the information to the user. The display device  503  is also used for displaying the nutrition information of the selected food to the user, and displaying the nutrition/energy the user consumed. Input device  504  is used for allowing the user to input the nutrition information, such as the nutrition information of the selected food, the nutrition/energy taken, or the nutrition/energy consumed. Step counter/Pedometer  505  is used for counting the steps the user taken, and sent the counts to Processor  501 . Process  501  calculates the nutrition/energy consumed based a given algorithm, and add up it to Memory  502   d.  For example, if the user walked at the leisurely pace of 3 miles in hour, the system/device (or processor) will tell the storage  502   d  the user had consumed about 300 calories. If at a certain time, for example, by the end of the day, the system will check the nutrition/energy needed, the nutrition/energy consumed, and the nutrition/energy taken. If the nutrition/energy taken−the nutrition/energy consumed&gt;the nutrition/energy needed, then the system will show a warning message from the display  503  or the like (such as the speaker). The user, after getting the warning message, will take some actions, such as another round walk. Then, the step counter will send more counts, which the user took, to the processor  501 . Process  501  will, then, the new nutrition/energy consumed data to the storage  502   d.  The system will check they nutrition/energy needed, the nutrition consumed, and the nutrition taken, and comparing them. If the nutrition/energy taken—the nutrition/energy consumed&lt;=the nutrition goal/need, the system will remove the warning message, or give good message like “Have a good night, you have taken a balanced diet today”, or even give special ring/tone telling the user whether or not he has taken a balanced diet today. If not, the system may also show message or give a special ring asking he or she to do more exercise to consume/burn the extra nutrition/energy. 
         [0083]      FIG. 6  shows another example of the nutrition/diet control system in accordance with the present invention.  600  is the cell phone (or the like such as blackberry or other mobile device) of the present invention, which includes a processor  601 , a storage/memory  602 , a display screen  603 , a speaker  604 , an antenna  605 , a keypad/input device  606 , and the other necessary cell phone parts/units  607 , such as the keypad, receiver, battery, and etc. According to the present invention, the cell phone  600  further includes a step counter/pedometer  609 , for walking and jogging. When a user walks or jogs while he or she is holding the cell phone  600 , the step counter/pedometer  609  will count the steps the user took. Many people, at the most time, just put the cell phone in the cell phone case that is attached to the belt of the user. Therefore, the step counter/pedometer  609  will count the steps whenever he or she walks or jogs. The data bus  610  connects the above parts to each other. Storage/Memory  602  further includes the means for storing the nutrition information, the nutrition/energy taken, and the nutrition/energy consumed. The user can input the nutrition facts/energy taken into the storage  602  in the cell phone  600  through the keypad or the other methods. According to the present invention, the step counter/pedometer  609  counts how much the cell user walks. The processor  601  processes the data provided from the step counter/pedometer  609 . According to the present invention, cell phone  600  is able to, through the antenna  605 , send their nutrition/diet information, which include the nutrition/energy taken and the nutrition/energy consumed, to a host server, such as the host server for a hospital, a diet club, or an insurance company. In cell phone  600 , the system or program will periodically send the user&#39;s nutrition/energy information to the hospital or the insurance company&#39;s or the fit club&#39;s server through the network connection, such as wireless connection. Therefore, the doctors in the hospital, the instructors in the diet club, or the persons in the insurance company will receive the nutrition information about their patients, club members, or their clients. For example, insurance company may lower the insurance fee for their clients based on how many steps they take per day. The processor  601  will check the nutrition/energy taken and the nutrition/energy consumed frequently. If the difference between the nutrition/energy taken and the nutrition/energy consumed is larger than the necessary nutrition/energy or the predefined certain level/the user&#39;s nutrition goal, it will show a warning message, on the display screen  603 , to the user at certain time, such as when every time he or she starts to use the cell phone, or every evening before going bed. The message will remind the cell phone holder to exercise in order to burn off the extra calories. According the doctors/nutrition experts, based on some certain condition, such as weight or height, a person needs to take at least a certain amount (standard level) of exercise. In reality, most people will select walking for their exercise to burn the calories. According to the present invention, the step counter/pedometer will automatically record the steps, such the daily total steps, into the user&#39;s weigh watch/diet control system. The storage/memory  602  also stores the data/information (standard level) recommended by the doctors or the nutrition experts for comparing. The storage/memory  602  also stores the history about nutrition information, include energy taken, such as the nutrition facts taken, and the energy consumed, such as the steps taken, for a long term weight watch/nutrition control for the cell phone holder. The cell phone holder can simply use the keypad/input device to enter the nutrition/energy taken into to the cell phone, and store the nutrition/energy taken data into storage/memory  602 . Therefore, the nutrition or diet control device according to present invention is capable, based on the comparing among the standard required nutrition/energy recommended by the doctors or the nutrition experts, the nutrition/energy taken, and the nutrition/energy consumed/burned, to give a better suggestion to the users, and show a warning message on the cell phone screen, or from cell phone speaker, or even give a special ring to the user to telling whether or not he has take a balanced diet today. According to the present of the invention, the storage/memory  602  further includes means for storing the allocation of the standard required nutrition/energy, the nutrition/energy taken, and the nutrition/energy consumed into a small time phase, for example, morning, afternoon, and night. 
         [0084]    In this case, if the user just eats more in his lunch, the system will suggest him to do more exercise in the afternoon. Therefore, the nutrition/diet control device according to the present invention is able to give the user a better, more accurate/prompt suggestion on their taking nutrition/energy and consuming the nutrition/energy, and help the user to have a good strategy on his or her nutrition/diet control. According the present invention, the storage/memory  602  further include means for storing the information for activities and the calories burned through the activities. For example, washing your car by hand will burn 200 calories, playing TaiJi for 30 minutes will burn 250 calories, doing Yoga for 30 minutes will burn 200 calories. Based on how many extra calories need to be burned and the user preferred activities, the system/processor will lookup from activity storage means and give the user suggestions about what activity or activities the user should take. For example, at evening time, if the user still has 200 extra calories need to be burned, system/processor find out that 30 minutes TaiJi will burn 250 calories, and it will show a message or ring to the user and suggest that he or she should take 30 minutes TaiJi. 
         [0085]    The best practice of weight control is to pay attention to what you eat and keep doing enough exercise. The cell phone with the nutrition/energy control function according to the present invention will definitely help the million users to control their weight. 
         [0086]      FIG. 7  is the flow chart showing how the device in  FIG. 6  works. 
         [0087]      FIG. 8  is another flow chart showing 
         [0088]      FIG. 9  depicts a hierarch tree structure. The tree shows how the different foods and the activities might be listed after having been organized by the hierarch tree. The user can easily select the foods he or she taken, and input it into the weight watch/diet control device. In the example shown, the first node in the root meal, the second node is snack/drink, and the third node is the activity. Thus, a user browsing would first select “Meal”, then select fast food, and then choose “Burger King Whopper”. The user can just use arrow up/down keys for entering the food he or she taken into the weight watch/diet control device. Same, the user can easily enter the how much energy he or she burned into the weight watch/diet or nutrition control. The weight watch/diet control device in accordance with the present invention also stores the nutrition/energy data for each food in its storage/memory so that it will convert the food taken into nutrition/energy information automatically, and use the nutrition/energy data to compare with the nutrition/energy needed, the nutrition/energy taken, and the nutrition/energy consumed, and then gives the user a better suggestion on his or her weight watch/diet or nutrition control. Before displaying the food/meal name in pull-down menu, system will, first, check the nutrition information and the user&#39;s nutrition goal/requirement, and then only shows the food/meal which meet the user&#39;s nutrition goal/requirement. For example, if user&#39;s nutrition goal for breakfast is 250 calories, the system will never show Big Mac on the menu for the breakfast for the user.
