The present invention is a jig system for precisely positioning the placement of multiple cuts such as in the placement of dovetail or box joints cut in a wood panel. A row of multi-use adjustable spacers controls the indexing of a workpiece and can be used with a stationary and/or a portable cutting tool. The movability of the spacers permits a workpiece to be cut on both sides of a guide bar fence thereby assuring that the first cut will always be made on the same side of a drawer and will be esthetically pleasing regardless of the width of the workpiece. Additionally, the adjustability of the spacers accommodates any desired cutting tool height, angle and/or size. The jig system comprises: a stationary fixture; a spacer bar; a plurality of spacers engaged with the spacer bar, the spacers are adapted for lateral and rotational movement along the spacer bar thereby providing an engaged and non-engaged working mode; a sliding member adapted for lateral movement on the stationary fixture and for engaging at least one of the spacers in the engaged working mode; and means for holding the spacer bar and connecting the spacer bar to the stationary fixture while engaging with at least one of the spacers during the engaged working mode.

The present invention discloses a non-resilient tattooing needle and a tattooing device using the same. The needle comprises a barrel, a needle body, a needle base, a first connecting rod and a first connecting part. The first connecting part of the present invention reciprocates under an external force and thus drives the needle body, via the first connecting rod and the needle base, to reciprocate linearly in the barrel. The advantageous effects of the present invention are as below: instead of using a spring, a rubber band or a rubber ring to provide a resilient force, the needle of the present invention is driven by an external force directly which enables the needle to retract quickly; such a problem is avoided that resilient forces diminish or even disappear after long-term use of the spring, the rubber band or the rubber ring which causes the needle cannot retract. The present invention also provides a tattooing device comprising an electric motor, a handle housing, a second connecting rod and an aforementioned tattooing needle. When pushing out the needle body, the electric motor does not need to work against resilient forces. Therefore, both the current and power of the electric motor are kept stable which thereby greatly prolongs the service life thereof.

Methods and devices for use in gathering and analyzing data from a corpus of documents. A corpus of documents is initially scanned for words that qualify as entities according to user defined criteria. Multiple counters track the number of documents which mention specific entities. A database of entities mentioned in the documents is maintained and an entry for each entity in the corpus is placed in the entity database. The results are then presented to a user in a spiral form with the most important entity at the center of the spiral. The importance of an entity may be determined by either how many entities it is connected to or how many documents mention that entity. A connection exists between two entities if they are both mentioned in at least one document and the more documents mention two specific entities at the same time, the stronger the connection between those two specific entities. The result presentation to the user is capable of also visually representing connections between entities by connecting connected entities with lines. The strength of a connection can also be represented with the width of the line connecting two entities.
