1. A method for time-stamping a message to a mobile recipient, the method comprising the steps of:
receiving a message at a message center, the message intended for receipt by a given recipient;
detecting a location of the given recipient;
determining a time zone associated with a detected location of the recipient; and
creating a time-stamp for said message using said determined time zone.
2. The method of claim 1 comprising the further step of transmitting said message with said time-stamp from said message center to the recipient.
3. A method for sending a time-stamped message to a mobile recipient, the method comprising the steps of:
receiving a message at a message center in a first time zone;
determining a second time zone in which the mobile recipient is located;
creating a time-stamp based on said second time zone; and
sending said time-stamp and said message to the mobile recipient.
4. The method of claim 3 wherein said first and second time zones are different.
5. The method of claim 3 wherein said step of determining said second time zone comprises the step of:
determining a network node with which the mobile recipient is registered.
6. The method of claim 5 wherein said network switch comprises a switch providing wireless communication capabilities.
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 wheel grid comprising:
a cross bar;
a first arm supported at the cross bar and configured to move between a stowed position and a use position;
a second arm movably coupled to the first arm and configured to move between a stowed position and a use position; and
a cam supported at the second arm and configured to move the second arm from the use position to the stowed position.
2. The wheel grid of claim 1, wherein the first arm is substantially parallel with the cross bar in the stowed position and substantially perpendicular to the cross bar in the use position.
3. The wheel grid of claim 2, wherein the second arm is substantially parallel with the first arm when in the stowed position.
4. The wheel grid of claim 3, wherein the second arm is substantially perpendicular to the first arm when in the use position.
5. The wheel grid of claim 1, further comprising a powered actuator coupled to the first arm for moving the first arm between the use position to the stowed position.
6. The wheel grid of claim 5, wherein the powered actuator comprises at least one hydraulic cylinder disposed within the cross bar.
7. The wheel grid of claim 5, further comprising an unfolding mechanism for moving the second arm from the stowed position to the use position in response to the powered actuator moving the first arm from the stowed position to the use position.
8. The wheel grid of claim 7, wherein the unfolding mechanism comprises a latch coupled to the cross bar and a projection extending from one of the cam and the second arm, the projection is configured to engage the latch as the first arm moves from the stowed position to the use position.
9. The wheel grid of claim 8, wherein the latch is pivotally coupled to the cross bar and configured to swing upwardly when engaged by the projection as the first arm moves from the use position to the stowed position.
10. The wheel grid of claim 8, wherein the latch includes a lip configured to engage the projection.
11. The wheel grid of claim 7, wherein unfolding mechanism comprises a biasing element having a first end coupled to the first arm and a second end coupled to one of the cam and the second arm.
12. The wheel grid of claim 11, wherein the biasing element begins to urge the second arm into the use position when the first arm begins to move into the use position.
13. The wheel grid of claim 12, wherein the biasing element is a tension spring configured to be at least partially loaded when the second arm is in the stowed position and at least partially unloaded when the second arm is in the use position.
14. The wheel grid of claim 11, wherein the biasing element is at least partially disposed within the first arm.
15. A wheel lift system for use with a transporter vehicle, the wheel lift system comprising:
a boom assembly;
a cross bar supported at a distal end of the boom assembly;
a first arm movably coupled to the cross bar and configured to move between a retracted stowed position and an extended use position;
a second arm pivotally coupled to the first arm and configured to move between a retracted stowed position and an extended use position; and
a cam configured to engage the cross bar for moving the second arm from the use position to the stowed position.
16. The wheel lift system of claim 15, wherein the cam is coupled to the second arm.
17. The wheel lift system of claim 15, wherein the cam is integrally formed with the second atm.
18. A transporter vehicle comprising:
a movable chassis;
an extensible boom assembly supported at a rear portion of the chassis;
a cross bar supported at a distal end of the extensible boom assembly;
a first arm pivotally coupled to the cross bar and configured to move between a stowed position and a use position;
a second arm pivotally coupled to the first arm and configured to move between a stowed position and a use position;
a powered actuator configured to move the first arm between the stowed position to the use position; and
an unfolding mechanism configured to move the second arm from the stowed position to the use position in response to the powered actuator moving the first arm.
19. The vehicle of claim 18, further comprising a cam supported at the second arm and configured to engage the cross bar for moving the second arm from the use position to the stowed position.
20. The vehicle of claim 19, wherein the unfolding mechanism comprises a biasing element coupled between the first arm and the second arm and that is at least part concealed within the first arm.
