Abstract: A sewer cleaning system includes a water tank, a pump operatively coupled to the water tank, a water hose operatively coupled to the pump, a vacuum-generating system, a vacuum hose operatively coupled to the vacuum-generating system, and a debris tank having a forward bulkhead defining a fluid chamber. The bulkhead includes a debris sieve configured to allow water in the debris tank to flow through to the fluid chamber while retaining particulates in the debris tank. The sewer cleaning system further includes an extraction pump in fluid communication with the fluid chamber and configured to extract the water in the fluid chamber. The extraction pump is in fluid communication with the water tank so as to send the extraction water from the fluid chamber to the water tank for re-use. A method for cleaning a sewer line is also disclosed.

Abstract: A test component and method of operation thereof are provided, the test component being arranged in a test environment to issue a test sequence over a bus to a device under test. A configuration file is provided to specify the behaviour of the test component, the configuration file comprising a plurality of regions with each region specifying attributes for use in determining the test sequence. The method of the present invention comprises the steps of: (a) when a test sequence is required to be issued, causing the test component to select, based on predetermined criteria, one of a number of regions provided by the configuration file; and (b) using the constraint attributes for that selected region to generate the test sequence to be issued on to the bus.

A configuration file is provided to specify the behaviour of the test component, the configuration file comprising a plurality of regions with each region specifying attributes for use in determining the test sequence. A number of the regions specify constraint attributes defining allowable test sequences. The method of the present invention comprises the steps of: (a) when a test sequence is required to be issued, causing the test component to select, based on predetermined criteria, one of a number of regions provided by the configuration file; and (b) using the constraint attributes for that selected region to generate the test sequence to be issued on to the bus.
