DESCRIPTION OF THE PREFERRED EMBODIMENT
[0024] In Figs. 1 to 4 of the accompanying drawings there is depicted
schematically a digital tape measure 1 which has a plastic casing 2. A steel tape 3
is mounted on a spring-loaded rotating spool 31 . The steel tape 3 has ordinary dimension marking printed on its top surface. These can be metric and/or imperial. A locking and unlocking mechanism 51 is provided. A printed circuit board (PCB) assembly 21 is provided. A liquid crystal display (LCD) unit 6 is provided. A battery compartment 7, key switches 8, 9, 10 are provided. A universal serial bus (USB) data receiver 1 1 is provided. A laptop or desktop computer 12 is provided.
[0025] Small slots 33 are cut evenly alongside the rim of one of the circular walls 32 of the tape spool 31 . This is located next to the PCB 21 . A photo sensor comprises a receiver 22a located at one side of the wall 32 and a light source 22b located at the other side of the wall 32 (hereinafter collectively referred to as "photo sensor 22"). Photo sensor 22 is mounted on the PCB 21 . When the tape 3 is extended from the casing, the tape spool 31 will rotate and the slots 33 on near the rim of the wall 32 will pass through the photo sensor 22 in one direction. The movement of the slots 33 will be detected by the photo sensor 22. To account for the diminishing diameter of the measuring tape that remains wound upon the spool as the tape is extended, the CPU will apply an algorithm to convert the numerical data signals detected by the optical sensor 22 into linear dimensions which are then displayed on the LCD unit 6.
[0026] The spring loaded locking mechanism 51 will automatically lock the tape 3 when the pulling action of the tape stops.
[0027] When the release button 5 is pressed, the tape 3 will be retracted by the spring loaded tape spool 31 . The slots 33 on the wall of the spool will pass the photo sensors 22 again in an opposite direction. The travelling direction and distance will be detected by the photo sensor 22. The signal is again converted into data and calculated by the CPU and displayed on the LCD 6.
[0028] The key switch 8 will toggle the measured displayed dimensions between metric and imperial.
[0029] When the tape 3 is fully retracted, the displayed dimension on the LCD 6 should be zero. In case if there is any residual value remain on the LCD 6, by pressing key switch 9, any displayed value on the LCD 6 will be set to zero.
[0030] The system includes a garment inspection data recording, analysing and reporting software system to be installed on the laptop or desktop PC.
[0031] When a garment dimension is measured and displayed on the
LCD 6, pressing the key switch 10 will cause the dimension to be transmitted via a radio frequency transmitter on the PCB 21 , to the USB receiver 1 1 connected to a laptop or desktop computer 12. Typically the radio frequency would be in the range 2.4 - 2.4835 GHz under the SDTP protocol (Short Distance Digital
Transceiving Protocol), or SFP protocol (Static Frequency Pair) for example.
[0032] A software program is installed on the laptop or desktop computer 12. The program can run on Windows or other operating systems. The program can be used in a stand-alone or networked environment. The program can support different languages, including but not limited to English and Chinese.
[0033] The user can create a user name and login to the program with a unique password. The users can be categorized into different groups to access different levels of information from the program to perform different functions. There can be pre-set inspection templates and control charts and examples of these are depicted in Figs. 6 and 7.
[0034] The user can retrieve pre-set inspection templates from the program. Authorized users can create and add new templates in the program. Authorized users can input, change, and edit data on the templates. The program can detect, receive and read numerical data from a digital measuring device through a wired or wireless interface. The user, by using the digital measuring device, can take and store measured data in the program. There will be a visually displayed signal on the computer monitor to prompt the position on the template where the data will be received. There will be an audio signal to confirm that data has been received and stored. Data will be received and stored in a pre-defined sequence, and the user can override and change such sequence if needed, by using the computer keyboard or pointing device.
[0035] The received data can be analyzed. For example it could be compared to a pre-defined standard and tolerance level set. There will be visually displayed signal if received data is outside a tolerance level. Data can be plotted on pre-defined control charts (e.g. Run Charts). Completed inspection records can be stored, sorted and retrieved (e.g. by date, by inspector ID, by customer ID etc.). Received data can be deleted before records are confirmed and saved. Users can choose to input the data on the template using the computer keyboard, instead of via a transmission from the digital measuring device, if needed. Authorized users
can retrieve, view, organize, delete, copy and print stored records.
[0036] As will be appreciated, a single point non-contact detection and measurement system is provided. No coding marks or punched holes need be provided on the tape. Wireless data transmission allows maximum convenience and high efficiency. A multi-user networked software program allows storage and also enables analysis and management of inspection results.
[0037] It should be appreciated that modifications and alterations obvious to those skilled in the art are not to be considered as beyond the scope of the present invention. For example, rather than providing indicia on the spool 31 in the form of slots 33, and rather than providing optical sensor components 22a and 22b at both sides of the spool wall 32 as exemplified, printed reflective and/or non-reflective markings could be provided at a single side of the wall and both optical components could then be positioned at that same side. Furthermore, rather than optical means, physical means in the form of bumps and/or depressions could be provided to cooperate with a physical switch for example. Similarly, magnetic means could be provided to achieve the same end.
