Intellectual Venture I LLC, et al. v. Cannon Inc. et al., C.A. No. 13-473-SLR, January 23, 2015.

Robinson, J. Claim construction opinion issues. The court considers terms from six patents relating to optical sensor circuit modules.

The court construes the following claim terms:

1. “[M]onitoring a flow of current in said laser and in said bypass:”

3. “[S]can control signals:”
4.  ”[O]ptical sensor circuit module … capable of receiving [the] scan control signals … and converting the scan control signals to timing    control signals:”
5.  ”[T]iming control signals:”
6.  ”[C]onverting:
7.  ”[O]ptical sensor circuit module … capable of receiving scan control signals … converting the scan control signals to timing control signals … extraction of an analog image signal … and conversion of the analog image signal into digital image data:”
8.  ”[T]iming generator … capable of generating the timing control signals that control a generation of the analog image signal and a conversion of the analog image signal into the digital image data:”
9. “[S]electing an automatic image trigger condition:”
10. “[E]ntering a threshold level:”
11.  “[A]utomatically operating the image capture device to capture at least one digital image upon the automatic detection of the automatic image trigger condition meeting the threshold level:”
12.  ”[D]etermining a driving signal, a triggering signal, and a number of rotation steps according to a predetermined resolution, wherein a period TG of the triggering signal equals a period TM of the driving signal multiplied by the number of rotation steps N within the period TG:”
13.  ”[O]btaining a number of rotation steps for a motor and a period of a driving signal by checking a table and referring to a predetermined resolution, and obtaining a period of a triggering signal by means of the period of the driving signal and the number of rotation steps for the motor, wherein the period TG of the triggering signal equals the period of the driving signal TM multiplied by the number of rotation steps for the motor N within the period TG:”
14.  ”[O]btaining a number of rotation steps for a motor and a period of a triggering signal by checking a table and referring to a predetermined resolution, and obtaining a period of a driving signal by means of the period of the triggering signal and the number of rotation steps for the motor, wherein the period of the driving signal TM equals the period TG of the triggering signal divided by the number of rotation steps for the motor N within the period TG:”
15.  ”[N]umber of rotations steps [for the motor] N:”
16.  ”[S]ingle device:”
17.  ”[T]he demodulated data signal:”
18. “[S]pread spectrum:”
