Title: Exercising apparatus

Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     This invention relates to exercising and more particularly to the improved apparatus for enabling an operator to exercise, 
     Background of the Invention 
     Regular exercise d physical activity are extremely important and beneficial for long-term health and well-being. Some of the benefits of exercise and physical activity include a reduced risk of premature death, heart disease, high blood pressure, cholesterol nd a reduced risk of developing colon cancer and diabetes. In addition, the benefits of exercise and physical activity further include a reduced body weight, a reduced risk of depression and improved psychological well-being. 
     As such, various types of exercising equipment have been proposed by the prior art for enabling an operator to exercise. Currently used exercising equipment is difficult to use and requires the expertise of an instructor or a personal trainer to teach the user the proper techniques and usage of the equipment. The user must also remember the required settings for the equipment and understand when these settings should be changed as the physical ability and strength of the user increases. Unfortunately, because of these limitations in order for an individual to properly and effectively utilize the exercise equipment the supervision of an experienced trainer is required. 
     The need exists for an exercise device which minimizes the need for extensive instruction from a personal trainer or instructor. Further, a device capable of recording the progress of the user would enable the user to more easily match the settings of the device to the improvement in the physical condition of the user. The ability of the device to record strength, and personal physical condition of the user such as heart rate would further increase the value of the device to the user. By combining these features in a device which is simple to maintain would provide a significant contribution to the art. The following U.S. Patents are the examples of an attempt of the prior art to solve these problems. 
     U.S. Pat. No. 5,785,632 to Greenberg, et al. discloses an apparatus for providing feedback to a user of a weight stack machine having weights for lifting and an enclosure adapted for attachment to the weight stack machine.

When the reflective optical sensors  152 ,  154 ,  156  and  158  are not receiving a light emission, the reflective optical sensors  152 ,  154 ,  156  and  158  are switched off to terminate current flow. The result of the reflective optical sensors  152 ,  154 ,  156  and  158  switching on and off produce a pulse electrical signal. 
       FIG. 14  illustrates a first, second, third and fourth electrical signal  153 ,  155 ,  157  and  159  produced by the reflective optical sensors  152 ,  154 ,  156  and  158  respectively. After the pulse electrical signals are amplified and converted, both the angular displacement and the rotational direction of the sensor pulley  134  can be determined. The angular displacement of the sensor pulley  134  is converted to a count  161  per turn of the sensor pulley  134 . The rotational direction of the sensor pulley  134  is converted to a direction  163  of the sensor pulley  134 . 
     Each of the reflective optical sensors  152 ,  154 ,  156  and  158  and infrared LEDs  160 ,  162 ,  164  and  166  may include a Fairchild pin QRD1114 consisting of a combined infrared LED/photodetector  167 . The sensor pulley  134  includes alternating sectors of absorbent surfaces  148  and reflective surfaces  150  for absorbing or reflecting the infrared light emitted from the infrared LED/photodetector  167 . The sensor pulley  134  may be constructed of a black ABS pulley wheel  135  and have a nominal radius 45 mm. The alternating sectors of absorbent surfaces  148  and reflective surfaces  150  may be constructed by masking the black ABS pulley wheel  135  and spraying a white paint into the ovoids of the mask. Alternatively, a pad-printing may be used to apply the alternating sectors of absorbent surfaces  148  and reflective surfaces  150  to the sensor pulley  134 . The number of both absorbent surfaces  148  and reflective surfaces  150  positioned on infrared LED/photodetector  167  may include eighteen ( 18 ) wherein both absorbent surfaces  148  and reflective surfaces  150  have a width of 7.85 mm. The four infrared LED/photodetectors  167  are utilized at phase angles of 0, 45, 90 and 135 degrees and are placed at an angular pacing of 22.5 degrees to provide reliable position encoding with an angular resolution of 2.5 degrees. 
     The postscript program to generate a 36 half-element (number of alternating black and white surfaces) wherein the sensor pulley  134  has a nominal radius of 45 mm may include the following:
