Abstract: A dredge head assembly is disclosed. The assembly includes: a shroud having a generally open bottom end and a top end; a screen structure covering the generally open bottom end of the shroud; a suction pipe with a first end connected to the top end of the shroud and a second end configured to be operatively connected with a pump which induces suction; a handle connected to and extending from the shroud and having at least one grasping portion; and one or more vacuum relief valve assemblies, each comprising a valve, at least one opening configured to be in communication with water, and an actuation mechanism positioned to be accessible to a diver. Dredging systems and methods of dredging are also disclosed.

Abstract: A system and method for tracking items may store in memory first association data reflecting an association between an item tracking device and a beacon device when the item tracking device is within a predetermined range of the beacon device. The item tracking device may correspond to a first item, and the beacon device may correspond to an area that contains multiple items including the first item. Furthermore, the system and method for tracking items may periodically transmit sensor data to a database. The sensor data may be transmitted to the database from the beacon device to provide information about an environment of a group of items from the multiple items within the predetermined range of the beacon device.

Abstract: A shift lever indicator assembly is provided for use in conjunction with a shift lever having a pivot axis. The shift lever indicator assembly comprises a housing having a housing track. An indicator member having a flag portion is slidably located within the housing track. The indicator member also includes an indicator arm connected to the flag portion, the indicator arm being connected to the shift lever such that the flag portion will be moved about the pivot axis of the shift lever when the shift lever is moved while allowing the flag portion to move lateral to an arc about the pivot axis.
