Test equipment and portable test device
First Claim
1. A portable apparatus for detecting a dental condition in dental hard tissue by applying electrical stimulus to the dental hard tissue in a dental system and acquiring response of the dental system, the apparatus comprising:
- signal generation means;
signal receiving means;
signal processing means; and
electrode means which are, in use, applied to an outer surface of the dental hard tissue,wherein a generated signal is applied to the outer surface of the dental hard tissue by said electrode means, a response signal is detected by said electrode means and received by the signal receiving means, the applied and received signals undergo processing by the signal processing means,wherein the signal generation means and signal receiving means are configured to apply the electrical stimulus to the outer surface of the dental hard tissue having an impedance of at least 100 kOhms and wherein the signal processing means is configured to process the generated signal so as to detect a dental condition in the said dental hard tissue.

Abstract
The present invention relates to an equipment, device (10; 110) and apparatus for applying electrical stimuli to a system and acquiring a system response. According to the present invention there is provided a test equipment such as a portable test device (10; 110) for testing a system, the equipment comprising: signal generation means, signal receiving means, and signal processing means, wherein, in use, the signal generation means generates a signal to be applied to a system to be tested and the signal receiving means receives a response signal of the system, and the generated and response signals undergo processing by the signal processing means so as to provide a measure of a characteristic of the system, wherein further the generated signal comprises a plurality of periodic signals each of different frequency and phase and which are applied to the system simultaneously. The equipment finds particular use in the field of dentistry, but also finds other uses, e.g. in medicine and also in corrosion detection and battery testing.
