Definitions
- the door lock at the customer premises is electronic.
- the delivery driver couples the electronic key to the lock, and manipulates the key so as to unlock the lock (e.g., by entering a PIN number) .
- the driver can then open the door and make the delivery.
- the door lock is conventional, i.e., mechanical.
- Such installations commonly have a small vault mounted near the door containing a mechanical door key secured on a short tether.
- the vault has an electronic lock and is unlocked by the driver with the electronic key. The driver can then access the mechanical key and use it to open the adjoining door.
- Such electronic keys typically include a memory for logging access data (e.g., IDs of accessed locks, time of access, etc.) .
- This data can then be downloaded into a database so as to document which driver made a delivery to which customer at which time.
- access data e.g., IDs of accessed locks, time of access, etc.
- This data can then be downloaded into a database so as to document which driver made a delivery to which customer at which time.
- Various known coupling techniques can be used to download the data from the key to a computer on which the database is maintained, e.g., infrared coupling, magnetic coupling, inductive coupling, capacitive coupling, electrical contacts coupling, etc.
- optical scanner used for reading bar code information, as is widely used today.
- the bar code inventory data scanned into the key is downloaded into a database - either with the access data or separately - to provide further detail about the deliveries.
- Fig. 1 is a pictorial view of an electronic key with an optical scanner shown in relation to one type of device accessed by the key.
- Fig. 2 is a schematic block diagram of an electronic key.
- Fig. 3 is a pictorial view showing the key of Fig. 1 being used to scan optically encoded information on an object.
- Figs. 4, 5 and 6 are front, right side and pictorial views, respectively, of a key with an optical scanner according to a second embodiment.
- Fig . 7 is a front view of a key with an optical scanner according to a third embodiment, showing the optical scanner pivoted outwardly from the case in its operating position.
- Figs. 8, 9 and 10 are front, right side and pictorial views, respectively, of a stand shaped to receive the key of Figs. 4, 5 and 6 or Fig . 7.
- an electronic key is equipped with an optical scanning circuit that includes an optical scanning element.
- an optical scanning circuit that includes an optical scanning element.
- One such circuit which is suited to reading optically encoded information in the form of bar codes, includes a sapphire bar code sensor tip, a bar code reader sensor, and a bar code decoding chip, all of which parts are commonly available (e.g., Hewlett-Packard part numbers HBCS-A999, HBCS-1 570, and HBCR-1 610, respectively) .
- a common memory in the key can store both the access data and the bar code inventory data, or separate memories can be provided.
- One particular arrangement has 4-5K of memory allocated for storage of the bar code inventory data (e.g ., permitting storage of data about 1000 items, each encoded with a four byte bar code item number, accompanied by 4-byte data indicating the s ⁇ te(s) visited, and 4- byte data indicating the number of items) .
- Some electronic keys include LCD displays as a part of the key's user interface (Ul) .
- the software that implements the LCD Ul can be adapted to provide user controls useful for bar code scanning operations as well.
- Hardware keys can have dual functionality, serving, e.g., to effect an unlocking operation when the key is in a first (key) mode, and to effect a scanning operation when the key is in a second (scanner) mode.
- Buttons presented on a Ul display can likewise have dual functionality, or a Ul unique to the scanning mode can be presented.
- the "Display" button on a key serves, when in bar code mode, to initiate one or more bar code reading operations. After operating the button, the user is prompted to indicate (by operation of numeric keys or otherwise) the number of packages that will be scanned. Once this number is entered, the delivery driver then scans respective bar code from each of the packages, the logging of each bar code being confirmed by an audible beep. (The key can be toggled between key and scanner modes by repeated operation of a single button.)
- a key adapted in accordance with the present invention can be similarly used. Moreover, since the key also provides access control, data is additionally digitally logged to specify the location at which deliveries (or pick-ups) were made. (The user ID is also unambiguously indicated by key assignment and proper entry of the user's PIN code.) If desired, a bar code identifying a facility can be mounted on or near the door through which deliveries are made (preferably inside, so as to prevent vandalism), permitting the delivery driver to optically scan that data into the device as well.
- the preferred embodiment of the present invention provides enhanced functionality for electronic keys, permitting them to perform automated inventory tracking and management at only marginally increased cost, by making dual use of the key and/or its memory, and/or the coupling means, and/or the data collection database.
- this technology is not limited to use by delivery drivers and for use in tracking inventory.
- the facility is usually locked but is accessed periodically by technicians.
- An electronic lock can be used, just as in the delivery context detailed above.
- the technician can scan one of several bar codes positioned by the door indicating the purpose of the visit, e.g., to check the transmitter, to backup computer data, to check battery status, to check premises security, etc.
- the system can be configured to record the technician's activity at the cell transmitter site.
- Components at the site can be bar coded, and the technician can be required to scan the bar code of each component that is accessed, inspected, adjusted, replaced, etc. In the case of a replaced component, the technician scans both the component to be replaced and the replacement component.
- This information can be collected to provide a profile of the components that require service or replacement most frequently, the time required to service or replace a particular component, the time spent on service operations by a particular technician, etc.
- the electronic key 1 2 is shown in its relation to one exemplary type of secured access device, i.e., a key vault 1 6, with which it can be used.
- the vault 1 6 includes a body 20 and removable lid 1 8 and is constructed for outdoor use.
- lid 1 8 has a recess 1 8a within which key 1 2 is inserted to make electrical contact between key 1 2 and a lock mechanism in the key vault 1 6.
- the key 1 2 interfaces with other secured access devices, such as an electronic door lock, similarly.
- key 1 2 may communicate by infrared transmission in addition to or instead of direct electrical contact.
- key 1 2 has a case 1 3 with a keypad 24.
- the case 1 3 houses a CPU 26, RAM and ROM memories 28, 30, a battery 32, a calendar/clock circuit 34, a piezoelectric transducer 36 with associated modulator 38, a communications interface 40 and an optical scanning circuit 41 a.
- the case 1 3 may be constructed as a trim polycarbonate enclosure sized to fit conveniently in a user's pocket.
- An optical scanning element 41 b is positioned at the surface of the case 1 3 as shown in an upper left-hand corner of the key 1 2.
- the optical scanning element 41 b can be positioned at other locations, provided that ( 1 ) the key 1 2 can be conveniently held while executing a bar code reading operation and (2) the overall shape of the key 1 2 remains generally unchanged (such that the key 1 2 can still interface with secure access devices (such as the vault 1 6) .
- Fig. 1 (and schematically in Fig. 2), the upper left-hand corner of the enclosure is slightly rounded to facilitate moving the key 1 2 across a surface having a bar code with the optical scanning element 41 b being maintained in contact with or within a specified distance from the bar code.
- Fig. 3 shows a user holding the key 1 2 and moving it in a direction A across a bar code 90 on an object 92.
- the operative distance at which the key 1 2 can read the bar code 90 depends upon the particular type of scanning element 41 b used, and may range from approximately in contact with the object 92 to approximately one foot or more from the object.
- the optical scanning element 41 b includes a sapphire tip.
- the optical scanning element 41 b can use CCD or active laser technology, as just two examples. Active laser technology usually allows a greater operative scanning range, but has greater power requirements.
- the illustrated communications interface employs two electrical contacts 42a, 42b exposed on top of the key1 2, but other coupling arrangements (e.g. more than two contacts, inductive coupling, optoelectronic coupling, etc.) can alternatively be used.
- key 1 2 can include a small alphanumeric display (e.g., LCD) and/or one or more indicator lights (e.g., LEDs) .
- the communications interface 40 bidirectionally couples data signals between the key 1 2 and lid 1 8 in the form of modulation on a power signal provided from the electronic key 1 2 to lid 1 8.
- Key 1 2 can serve not only as an access key for the vault 1 6, but also as a data link-relaying data to and from the vault 1 6.
- CPU 26 can be an Intel microcomputer (e.g. 80C52) that controls operation of the key according to programming instructions permanently stored in
- the calendar/clock circuit 34 provides data corresponding to the year, month, day, and time.
- the illustrated RAM 28 is comprised of a small RAM memory inside the calendar/clock circuit 34, together with 2 EEPROMS, the latter of which can store 2048 (2K) 8-b ⁇ t bytes of data.
- Transducer 36 is used to provide audible feedback to the user signaling a variety of key conditions.
- the transducer can also be used for frequency shift keyed relaying of data from the key to external devices (e.g. through an audio telephone circuit) .
- Battery 32 can comprise three AAA cells which provide power to the key circuitry and, through contacting elements 42, to vault lid 1 8 as well.
- Figs. 4-6 show an electronic key 1 2' according to a second embodiment.
- the key 1 2' is similar to the key 1 2, except that the case 1 3' , display 14' and key pad 24' are shaped differently, and the key 1 2' includes an infrared transmitter or transceiver 43 that allow the key to communicate with secured access devices and to transfer data optoelectronically.
- the infrared transceiver In the key 1 2' , the infrared transceiver
- the infrared transceiver 43 is positioned on the case 1 3' between the contacts 42a, 42b.
- the infrared transceiver 43 is embodied as part of the communications interface circuitry 40.
- Fig . 7 shows an electronic key 1 2" according to a third embodiment.
- the key 1 2" is similar to the key 1 2' , but in the key 1 2", the bar code scanning element 41 b is attached to a pivoting member 45.
- the pivoting member 45 is attached to a side of the case 1 3 such that it can be pivoted outwardly to its operative position as shown in Fig . 7 or pivoted inwardly to its closed position within the outline of the case 1 3.
- the pivoting member 45 allows for scanning in some applications where clearances or interference might make use of the key 1 2 or the key 1 2' difficult.
- a suitable stand 80 shaped to receive the key 1 2' (or the key 1 2") is shown in Figs. 8-1 0.
- the stand 80 has a key receiving portion 82, contacts 84a, 84b (corresponding to the contacts 42a, 42b, respectively) and a telephone line connection 86 to a computer (not shown) .
- the stand is used to download access and scanned data from the key (via the contacts 42a, 42b and the contacts 84a, 84b) over the connection 86 to the computer
- the stand 80 can be configured to begin the downloading process automatically, i.e., without requiring the user to intervene (e.g., by pressing a button or similar operation), when the key 1 2' is received in the stand 80.
- connection 86 and the stand 80 can be used to upload information to the key 1 2' .
- One type of such information is programming updates to the key 1 2' functions.
- the stand can also be connected to a suitable power source and fitted with an appropriate AC/DC converter to recharge the battery 35, if desired.
- the keys 1 2, 1 2 ' and 1 2" as described above are dedicated devices, i.e., they function as secured access devices and optical scanners. However, it is also possible to embody all of the key and scanner functionality together in other handheld appliances, such as personal digital assistants and cellular telephones.
