A catalyst state detector for detecting a state of an exhaust gas purifying catalyst which is capable of accurately detecting the state, including deterioration, of an HC adsorbent contained in the exhaust gas purifying catalyst for adsorbing hydrocarbons in exhaust gases of an internal combustion engine, and can be manufactured at a low cost. The method includes receiving, at the electronic device, an update indication from a server that updated software is available for the electronic device. The table contains characters assigned to the total numbers of times the character input key is pressed down. The execution unit is to execute the instruction. The end effector is configured to clamp around a body organ or tissue and apply and confine biological sealant in a substantially uniform manner thereto. The motor controller includes a drive circuit that generates the drive signal.
