1. A multi-ownership tree-map visualization system comprising:
a tree-map configured to visualize a set of interrelated nodes in which at least one individual node in said set is related to at least two parent nodes in said set; and,
an event handler, executed by a hardware processor, programmed to process a proximity event associated with a specific portion of said tree-map by highlighting multiple portions of said tree-map in which said portions represent a single node in said set.
2. The system of claim 1, further comprising logic for displaying a call-out box for each portion of said tree-map associated with said single node in said set.
3. The system of claim 1, wherein said proximity event is selected from the group consisting of a mouse-over event, a mouse-click event, and a keyboard selection event.
4. A machine readable storage medium having stored thereon a computer program for presenting multi-ownership in a tree-map, the computer program comprising a routine set of instructions for causing the machine to perform the steps of:
detecting a proximity event about a representation for a node in the tree-map;
determining through said representation a unique identifier for said node;
locating all other representations in the tree-map which corresponding to said unique identifier; and,
highlighting each of said representations in the tree-map.
5. The machine readable storage medium of claim 4, wherein said step of highlighting comprises displaying a call-out box for each of said representations.
6. The machine readable storage medium of claim 4, wherein said detecting step comprises the step of receiving a mouse-over event in an event handler for the tree-map.
7. The machine readable storage medium of claim 4, wherein said detecting step comprises the step of receiving a mouse-over event in an event handler for said representation about which said proximity event is detected.
8. The machine readable storage medium of claim 4, wherein said detecting step comprises the step of receiving a mouse-click event in an event handler for the tree-map.
9. The machine readable storage medium of claim 4, wherein said detecting step comprises the step of receiving a mouse-click event in an event handler for said representation about which said proximity event is detected.
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, comprising:
monitoring at least one environmental characteristic associated with a location of a wireless signal receiver;
determining if the wireless signal receiver is likely to receive a wirelessly transmitted signal at the location, wherein the determination is based at least in part upon the monitored at least one environmental characteristic associated with the location of the wireless signal receiver; and
improving the performance of the wireless signal receiver based upon determining if the wireless signal receiver is likely to receive a wirelessly transmitted signal
wherein the at least one environmental characteristic comprises at least one of ambient temperature, luminosity level, and a received signal strength of a second wirelessly transmitted signal;
wherein the determining uses the at least one environmental characteristic in conjunction with at least one of a temperature table, time of day, and an approximate location for the wireless signal receiver.
2. The method according to claim 1, wherein the wireless signal receiver determines its location.
3. The method according to claim 1, wherein the improving inhibits a receiving function of the wireless signal receiver.
4. The method according to claim 1, wherein the improving lowers the power consumption of the wireless signal receiver.
5. The method according to claim 1, wherein the wireless signal receiver is operated in a non-periodic manner after the determining determines that the wireless signal receiver is not likely to receive a wirelessly transmitted signal, wherein the non-periodic manner is not a random back-off.
6. The method according to claim 1, wherein the temperature table comprises historical climactic data for the location for one or more time of year.
7. The method according to claim 1, wherein the improving is inhibited when operating in a priority mode.
8. The method according to claim 7, wherein the priority mode is an emergency telephone call.
9. An apparatus, comprising:
a wireless signal receiver;
an environmental monitor for monitoring at least one environmental characteristic associated with a location of the wireless signal receiver;
a receive likelihood estimator, communicatively coupled to the environmental monitor, for determining if the wireless signal receiver is likely to receive a wirelessly transmitted signal at the location, wherein the determination is based at least in part upon the monitored at least one environmental characteristic associated with the location of the wireless signal receiver; and
a receiver controller, communicatively coupled to the receive likelihood estimator and the wireless signal receiver, for commanding an operational mode change in the wireless signal receiver in response to a determination of whether the wireless signal receiver is likely to receive a wirelessly transmitted signal, wherein the operational mode change improves the performance of the wireless signal receiver;
wherein the operational mode change comprises operating the wireless signal receiver in a non-periodic manner, wherein the non-periodic manner is not a random back-off.
10. The apparatus according to claim 9, wherein the wireless signal receiver is a geo-positioning receiver.
