Abstract

A remote display system including a portable display that wirelessly receives data and power from a primary station. The primary station, which is remote from and without a tangible connection with the portable display, includes a data transmitting element and a power transmitting element. The portable display includes a power receiving element that receives power wirelessly from the power transmitting element and a data receiving element operable to receive data from the data transmitting element.

First claim

What is claimed is:

1. A computer implemented method, comprising:
under control of one or more computer systems configured with executable instructions,
detecting that a portable display is within range of a first primary station of a plurality of primary stations, the portable display including a power receiving element and a data receiving element, wherein the first primary station includes a data transmitting element and a power transmitting element;
wirelessly receiving power from the power transmitting element of the first primary station through the power receiving element of the portable display;
wirelessly receiving a first data signal from the data transmitting element of the first primary station through the data receiving element of the portable display; and
displaying, on the portable display, first data corresponding to the first data signal while powering the portable display using the power that was received from the first primary station;
detecting that the portable display is within range of a second primary station of the plurality of primary stations, wherein the second primary station includes a power transmitting element and a data transmitting element;
determining that a difference in power signal strength between a first power signal of the first primary station and a second power signal of the second primary station exceeds a first threshold for wirelessly receiving power from the power transmitting element of the second primary station and through the power receiving element of the portable display;
wirelessly receiving power from the power transmitting element of the second primary station through the power receiving element of the portable display;
determining that a difference in data signal strength between the first data signal of the first primary station and a second data signal of the second primary station exceeds a second threshold for wirelessly receiving data from the second primary station through the data receiving element of the portable display;
selecting a different primary station of the plurality of primary stations from which to receive data based at least in part on the difference in data signal strength exceeding the second threshold, the different primary station being separate from the second primary station;
wirelessly receiving second data from a data transmission element of the different primary station through the data receiving element of the portable display; and
updating the portable display to display the second data received from the different primary station while powering the portable display using the power that was received from the second primary station.

2. The computer implemented method of claim 1 , further comprising:
transmitting a connection request from the portable display to the second primary station.

3. The computer implemented method of claim 1 , further comprising:
detecting a presence of a minor within a proximity of the portable display by a security feature included in at least one of: the portable display, the first primary station, or the second primary station; and
limiting at least one of: content displayed on the portable display or functionality accessible by the portable display in response to detecting the presence of the minor within the proximity of the portable display.

4. The computer implemented method of claim 1 , further comprising:
transmitting a request for a first set of content from the portable display to the second primary station, the first set of content having an identifier associated therewith;
transmitting the first set of content from the data transmitting element of the second primary station to the data receiving element of the portable display;
determining, based at least in part on the identifier, a second set of content likely to be requested by the portable display in a subsequent request; and
transmitting the second set of content from the data transmitting element of the second primary station to the data receiving element of the portable display prior to receiving the subsequent request from the portable display.

5. The computer implemented method of claim 1 , wherein the portable display is mounted on at least one of: a windshield of an automobile or a user's glasses;
and wherein the portable display is at least partially transparent.

6. A remote display system, comprising:
a plurality of primary stations;
a first primary station of the plurality of primary stations including a data transmitting element operable to wirelessly transmit data and a power transmitting element operable to wirelessly transmit power;
a second primary station of the plurality of primary stations including a data transmitting element operable to wirelessly transmit data and a power transmitting element operable to wirelessly transmit power; and
a portable display including a power receiving element and a data receiving element,
the portable display operable to:
determine that the portable display is within power transmitting range of the first primary station;
wirelessly receive the power from the power transmitting element of the first primary station;
display first data corresponding to a first data signal received from the first primary station while powering the portable display using the power received from the first primary station;
determine that a difference in power signal strength between a first power signal of the first primary station and a second power signal of the second primary station exceeds a first threshold;
wirelessly receive the power from the power transmitting element of the second primary station;
determine that a difference in data signal strength between the first data signal and a second data signal received from the second primary station exceeds a second threshold;
select a different primary station of the plurality of primary stations from which to receive second data based at least in part on the difference in data signal strength exceeding the second threshold, the different primary station being separate from the second primary station;
wirelessly receive the second data from a data transmission element of the different primary station through the data receiving element of the portable display; and
update the display to display the second data received from the different primary station while powering the portable display using the power received from the second primary station.

7. The remote display system of claim 6 , wherein the portable display is further operable to transmit a connection request to the second primary station.

8. The remote display system of claim 6 , wherein at least one of: the portable display, the first primary station, or the second primary station further includes:
a security feature operable to detect a presence of a minor within a proximity of the portable display, and limit at least one of: content displayed on the portable display or functionality accessible by the portable display in response to detecting the presence of the minor within the proximity of the portable display.

9. The remote display system of claim 6 , wherein the portable display is further operable to:
transmit a request for a first set of content to the second primary station, the first set of content having an identifier associated therewith; and
receive the first set of content from the data transmitting element of the second primary station to the data receiving element of the portable display; and
wherein the second primary station is operable to:
determine, based at least in part on the identifier, a second set of content likely to be requested by the portable display in a subsequent request; and
transmit the second set of content to the data receiving element
