Optical reader system comprising host processor and optical reader
First Claim
1. An optical reader in communication with a spaced apart host processor, said optical reader comprising:
- (a) an imaging assembly including a two dimensional solid state image sensor and an optical assembly focusing an image of a target onto said solid state two dimensional image sensor;
(b) a memory;
(c) an analog to digital converter coupled to said two dimensional solid state image sensor and converting signals from said solid state two dimensional image sensor into a plurality of gray scale values for storage into said memory;
(d) a controller coupled to said imaging assembly, said memory, and said analog to digital converter, where said controller is configured to capture frames of image data into said memory; and
(e) a hand held housing encapsulating said imaging assembly, said memory, said analog to digital converted, and said controller, said hand held housing being adapted to be held in human hand so that said hand held housing is freely movable between a variety of positions relative to said spaced apart host processor;
(f) wherein said optical reader is configured to operate in a first mode in which said optical reader receives from said spaced apart host processor a trigger instruction, wherein said controller substantially on receipt of said trigger instruction stores a frame of image data into said memory, and automatically attempts to decode a decodable bar code symbol represented in said frame of image data;
(g) wherein said optical reader is further configured to operate in a second mode in which said optical reader receives from said spaced apart processor a frame upload instruction, wherein said controller substantially on receipt of said frame upload instruction uploads a lasts captured image data of said reader to said space apart host processor.

Abstract
The invention relates to an optical reading system comprising an optical reader and a host processor. In one aspect of the invention, the host processor may be configured to transmit a component control instruction in response to a user input command input by a user of the host processor to remotely control the reader. The optical reader subsequently receives the transmitted component control instruction and executes the component control instruction substantially on receipt thereof. In one embodiment, execution of the component control instruction by the optical reader has the same effect as the reader trigger being manually pulled by a reader operator.

9. An optical reader system comprising:
-
(a) a hand held optical reader including an imaging assembly having a two dimensional solid state image sensor, an optical assembly focusing an image of a target onto said two dimensional solid state image sensor, a memory, a controller configured to capture a frame of image data representing a two dimensional area image into said memory, a trigger, and a hand held housing supporting said imaging assembly;
(b) a host processor spaced apart from said hand held optical reader; and
(c) a communication link facilitating data communication between said host processor and said hand held optical reader;
(d) wherein said hand held housing is adapted to be grasped by a human hand so as to be moveable between variable positions relative to said spaced apart host processor;
(e) wherein said hand held optical reader is configured to receive from said spaced apart host processor a trigger instruction, and wherein said hand held optical reader is configured to operate in a mode in which said hand held optical reader is responsive to both of an actuation of said trigger and a receipt of said trigger instruction from said spaced apart host processor so that substantially on receipt either of a signal ensuing from an actuation of said trigger or of said trigger instruction from said spaced apart host processor said controller captures a frame of image data representing a two dimensional area and automatically attempts to decode decodable bar code symbols represented in said frame of image data. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
