DETAILED DESCRIPTION OF THE INVENTION

(10) One purpose of the workout sensing system is to provide data corresponding to a user's exercise that enables logging, tracking, and analysis of the user's exercise routine. A layer of software, which may be artificial intelligence software, may then analyze a user's workout data and suggest workouts.

(11) FIG. 1 shows an overview of how multiple workout sensing systems might communicate with other devices. In this example, the workout sensing system 150 may be incorporated into a piece of strength training workout equipment at a gym, or some other workout device. For example, the workout sensing system 150 of the present invention may be incorporated into a barbell, lat bar, or row bar.

(12) In one embodiment, a user may identify oneself to the workout sensing system 150 with a user identification device 151. An example of a user identification device 151 may be a near field communication enabled card, a smartphone, or a watch. The workout sensing system 150 may then send workout data to a local display 153 and/or, optimally, to a local server 154. Local display 153 may be a user's smartphone, a tablet, or a display in the gym, or any other device, or it may not be present. One way in which this process can occur is as follows: Local server 154 would collect data from multiple workout sensing systems 150, then send it to a remote website/cloud 155. The website/cloud 155 would then analyze the data and display it to the user via a mobile app or web browser.

(13) Referring to FIG. 2, the workout sensing system 150 may be embedded in a piece of strength training workout equipment 203. The workout sensing system 150 consists of components which are electrically connected including detector(s) 202, 209, 210, 211, and 212, a processor 206, an internal display 205 and/or an external display 208, and a data-logging device 213. A battery 204 may be used to power a processor 206, detector(s) 202, 209, 210, 211, 212 and display 205/208. The detector 209 may be an accelerometer, an inertial measurement unit or other device well known in the art. The detector 202 is for example a load cell, an array of multiple load cells, a strain gauge or an array of multiple strain gauges, or a pressure sensor. The display 205/208 is for example a liquid crystal display or any other device to display data to the user. The detector 210 is for example an inertial measurement unit, a lidar range finder, or an ultrasonic range finder. The detector 211 is for example a real-time clock. The detector 212 is for example a near field communication transceiver, WiFi or a BLUETOOTH communication transceiver, fingerprint scanner, or facial recognition detector. Multiple accelerometers may be used (e.g., triaxial accelerometer). Where a remote display is used, a wireless communication transceiver may also be used. The data logging device 213 may be a server, and may communicate with processor 206 via wireless communication.

(14) FIGS. 3A and 3B illustrate different exemplary embodiments of workout sensing system 150 in accordance with the present invention.

(15) FIG. 3A is a cross-sectional side view of one part of an exemplary barbell embodiment 303 incorporating the workout sensing system 150 of the present invention. A weight 310 is shown on barbell 303 (note, weight 310 is shown in FIG. 3A for illustrative purposes). The detectors 202, are an exemplary part of a detector array. Each detector 202 is for example a load cell, a strain gauge, or a pressure sensor. The rest of workout sensing system 150 may be embedded in within the sleeve of the barbell, location 311, or another location on the bar.

(16) FIG. 3B shows another exemplary barbell embodiment incorporating the workout sensing system 150. It will be understood that this embodiment is similar to the embodiment in FIG. 3A to the extent not otherwise described herein. The two embodiments differ by incorporating a different implementation for force detection. The detectors 202 detect load and may be a load cell, pressure sensor, strain gauge, or more specifically a spoke type load cell. A sleeve 309 has a larger diameter on one end to accommodate detector 202. The bar 303 has a reduced diameter on the end to accommodate detector 202.

(17) FIGS. 4A, 4B, and 4C, show one embodiment of the workout sensing system 150 described in 3A.

(18) FIG. 4A shows an end view of one part of an exemplary device 303 embedded with the workout sensing system 150. In the embodiment illustrated, the device 303 may include a plurality of detectors. For example, the device 303 may include a group of four detectors 202 is shown. More or less detectors 202 may be incorporated in the system. Detectors 202 may be arranged around the axis of bar 303. Other examples of an array of detectors 202 could include any quantity of detectors. Sleeve 309 distributes load across detectors 202.

(19) FIG. 4B is the same view as FIG. 4A, however it shows another exemplary array of two detectors 202.

(20) FIG. 4C is the end view similar to FIG. 4A and FIG. 4B, however, this view corresponds to the device described in FIG. 3D. FIG. 4C describes one example of detectors 202. In this example, detectors 202 are spoke type load cells.

(21) Referring to FIG. 5, schematically illustrates an overview of the data processing. Processor 206 samples multiple detectors in step 502, processes the signal in step 503, and transmits the data to a logging device or a display in step 504, either embedded or remote. The following paragraphs describe specific exemplary processes that may be executed by processor 206.

(22) In an embodiment of process 500, the detector that is sampled in step 502 is an accelerometer and therefore the physical metric is acceleration. In step 503, the processor 206 processes the physical metric to assess whether the metric indicates repetition of the device. In step 704 repetition information is displayed to the user.

(23) In another embodiment of process 500 the detectors sampled in step 502 are an array of load cells and an accelerometer. The physical metrics are therefore strain and acceleration. In step 503, these physical metrics will be processed to determine the force vector exerted on the device. This is determined by calculating the acceleration vector of the device and the individual force vectors for each detector (detector configurations may be as shown in FIG. 3A, FIG. 4A, FIG. 4B, FIG. 4C or as shown in FIG. 3B). By summing the components of each force vector that are parallel to the acceleration vector, the magnitude of the force vector may be determined then displayed in step 504.

(24) Another embodiment of process 500 may determine and display the mass connected to the device. For this process, force may be determined as previously described. The detector that is sampled in step 502 may be an accelerometer and therefore the physical metric is acceleration. This physical metric may be processed in step 503 to determine the acceleration vector of the device. Weight connected to the devices can be calculated by processing the force and acceleration vectors to determine mass. This step 503 may be, for example, dividing force by acceleration to determine mass, which may then be displayed in step 504.

(25) Another embodiment of process 500 may determine the maximum displacement during a repetition. An accelerometer may be sampled in step 502 and therefore the physical metric is acceleration. In step 503 this physical metric will be processed to determine the maximum displacement during a repetition. This process may, for example, be a double integration. The maximum displacement may then be displayed in step 504.

(26) Another embodiment of process 500 may determine the average power over the span of a repetition. An accelerometer may be sampled in step 502 and therefore the physical metric is acceleration. Force may be calculated in step 503 as previously shown, along with the accelerometer data to determine average power over a repetition. This data may then be displayed in step 504.

(27) Another embodiment of process 500 may determine the duration of a repetition or set of repetitions. A real time clock may be sampled in step 702, and therefore the physical metric is time. Duration of a repetition may then be determined in step 503 and displayed in step 504.

(28) Another embodiment of process 500 may determine the identification of a user. The detector may be a wireless transceiver, a fingerprint scanner, or a facial recognition module. The physical metric to be sampled in step 502 would correspond to the detector utilized. The identification of the user may then be determined in step 503 and displayed in step 504.

(29) Referring to FIG. 6, describes an embodiment of a process 600 that a detector may use to determine the force placed on a device. This process 600 compensates for the orientation of the device. In step 601, an array of load cells and an accelerometer are sampled. In step 602 the orientation of the device is determined. In step 603, the load cell data is adjusted based on the orientation of the device. For example, if the device is connected to a 100 kg mass was rotated 45 degrees away from direction of the applied load, then the load data before compensation may read 70.7 kg. After compensation, the load data would read 100 kg (e.g., 70.7/cos(45)=100.

(30) In an embodiment that utilizes spoke type load cells for detectors 202 as described in FIG. 4C, load on the bar can be determined. Load on each cell is determined by measuring the compression and tension forces in each spoke of the load cell. By summing up these forces, load on the cell is determined independent of the direction the load is applied, and is therefore independent of the orientation of the device. For example, a load cell measuring a 10 lb load from a set direction would output the same signal even if the load cell were rotated 45. By averaging the outputs of detectors 202, load on the device is determined.
