Scan driver and driving system with low input voltage and their level shift circuit are disclosed. The scan driver includes a latch unit, a level shift circuit and a buffer. The latch unit generates a first control signal and a second control signal. The level shift circuit is connected to the latch unit to receive the first control signal, the second control signal, a first clock signal and a second clock signal, so as to output a scan signal with high voltage level. The buffer enhances driving ability of the scan signal for driving thin-film transistors (TFTs) of a display panel.

Disclosed is a source follower with Vgs compensation, such that the output voltage precisely follows the input voltage by various arrangements of MOSFET's, switches, and capacitors. In addition, such a source follower that the output voltage precisely follows the input voltage can be implemented without adding too many components. The source follower disclosed in the present invention can be used in the driver circuit for a liquid crystal display (LCD).

A method for tracking modifications to tables or relationships. In one embodiment, the method includes updating a first value stored in a first field of a record in a table in response to a database system receiving a first structured query language (SQL) statement from a customer relationship management (CRM) application. A first record is inserted into a history table in response to the first SQL statement, wherein the first record comprises a foreign key field that stores a copy of the primary key of the record, a field that stores a copy of the first value after it is updated, a field that stores a name of the first field, and a first date field. The first date field stores either the date when the first SQL statement was received by the database system, the date of the day that immediately follows the date when the first SQL statement was received by the database system, or a date that was entered into a field of a user interface.

Systems and methods to provide an availability and price determination, in response to a request for function space, to a user in real-time. For one embodiment, a request for a function space is received at a digital processing system that contains availability information and a set of pricing rules for one or more function spaces. The request includes a plurality of criteria. An availability of the requested function space is determined based upon the availability information and one or more of the criterion. A price for the requested function space is determined based upon the set of pricing rules and one or more of the criterion.
