1. A method for fastening a cord lock device on a fabric, comprising the following steps of:
(a) providing a cord lock with at least one through hole in which at least one cord may pass, wherein the cord lock has an inner lateral wall extended upwards from a lower surface thereof to an inner surface thereof to define a recess portion;
(b) providing a buckling element, wherein the buckling element has a protrusion protruded upwards from an outer surface thereof;
(c) disposing the buckling element on the fabric via the protrusion passing an aperture of the fabric; and
(d) fastening the cord lock onto the buckling element and the fabric via the protrusion received in the recess portion.
2. The method as claimed in claim 1, wherein the step (a) comprises the following step of:
(a1) forming a plurality of convex dots on the lower surface of the cord lock.
3. The method as claimed in claim 1, wherein the step (a) comprises the following step of:
(a2) forming a non-flat surface on an upper surface of the cord lock.
4. The method as claimed in claim 1, wherein the protrusion comprises two side walls to form a groove.
5. The method as claimed in claim 4, wherein the step (b) comprises the following step of:
(b1) arranging a snap-fit end of an outer end of each of the side walls to buckle the inner surface of the cord lock when the protrusion is received in the recess portion.
6. The method as claimed in claim 5, wherein the step (b) comprises the following step of:
(b2) forming a plurality of convex dots on the outer surface of the buckling element.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for monitoring continual range queries against events, said method comprising:
decomposing each range query into one or more predefined virtual constructs;
building a query index; and
using said query index to match an event with said range queries.
2. The method of claim 1, said building of a query index further comprising:
storing an identification of said query with identification lists associated with said virtual constructs.
3. The method of claim 1, said building of a query index further comprising:
predefining a set of virtual constructs for each point being monitored.
4. The method of claim 1, said matching of an event with said range queries further comprising:
finding all the virtual constructs that cover said event.
5. The method of claim 1, said decomposing of a range query further comprising:
initializing a working rectangle to be said range query;
repeatedly cutting a strip rectangle from said working rectangle; and
decomposing said strip rectangle with one or more of said virtual constructs.
6. The method of claim 4, wherein the size of the set of covering virtual constructs of an event is constant for all the event points.
7. The method of claim 4, wherein gaps between corresponding different covering virtual constructs of all event points are identical.
8. The method of claim 4, said finding of all covering virtual constructs of an event comprising:
pre-computing of a difference table;
computing the identification of a pivot virtual construct; and
adding said identification of pivot virtual construct to each of the elements stored in said difference table.
9. A method of providing a service of monitoring events or conditions, said method comprising at least one of the following:
providing a service that monitors events against interests of a customer, said service monitoring said events by decomposing continual range queries related to said customer interests with one or predefined virtual constructs, building a query index, and using said query index to match an event with said range queries;
maintaining one or more customer interests expressed as continual range queries for the service that monitors events; and
notifying a subset of said customers whose interests match an event.
10. A system for monitoring continual range queries against events, said system comprising:
a decomposing module that decomposes each range query into one or more predefined virtual constructs;
a query index construction module; and
an event matching module that uses said query index to match an event with said range queries.
11. The system of claim 10, further comprising:
at least one sensor to detect occurrence of events.
12. The system of claim 10, further comprising:
at least one client input station to permit a client to provide an input query.
13. The system of claim 10, further comprising:
at least one client receiver to permit a client to be notified of occurrence of an event of interest.
14. An apparatus for monitoring continual range queries against events, said apparatus comprising one of:
a query monitor that includes:
a decomposing module that decomposes each range query into one or more predefined virtual constructs;
a query index construction module; and
an event matching module that uses said query index to match an event with said range queries;
a sensor to detect occurrence of events and provides said occurrence of events into said query monitor;
a client receiver to permit a client to be notified of occurrence of an event of interest to said client.
15. A signal-bearing medium tangibly embodying a program of machine-readable instructions executable by a digital processing apparatus to perform a method for monitoring continual range queries against events, said method comprising:
decomposing each range query into one or more predefined virtual constructs;
building a query index; and
using said query index to match an event with said range queries.
