Operation of Circuit Breaker with the help of Password

A circuit breaker is an electrical switch use to protect an electrical circuit from damage caused by faults. Its basic function is to detect a fault condition and protect from it. Fuse operates once after that it must be replaced but a circuit breaker can be reset to resume normal condition. During the manual operation, we see inoperable electrical accidents to the line man are rises during maintenance due to improper communication between the maintenance staff and the substation staff. In order to prevent such accidents, password based circuit breaker is design so that only authentic person can operate it with a password. There is also a facility of changing the password. The system is fully controlled by the microcontroller. The password is saved in an EEPROM, interfaced to the microcontroller and the password can be changed any time. A keypad is used to submit the password and a relay to operate circuit breaker, which is indicated by a bulb. Any wrong attempt to open the circuit breaker by entering the wrong password an alert will be shown in the LCD

Clinical survey of 3680 iris tumors based on patient age at presentation.

OBJECTIVE: To report the spectrum of iris lesions based on patient age at presentation. DESIGN: Retrospective, nonrandomized, single-center case series. PARTICIPANTS: We included 3680 iris tumors in 3451 patients. METHODS: Chart review. MAIN OUTCOME MEASURES: Diagnostic category based on age. RESULTS: The mean age at presentation was 48 years and there were 449 (12%) tumors in children (≤20 years), 788 (21%) in young adults (21-40 years), 1308 (36%) in mid adults (41-60 years), and 1135 (31%) in senior adults (\u3e60 years). Of 3680 tumors, the diagnostic category was cystic (n = 768; 21%) or solid (n = 2912; 79%). The cystic tumors originated from iris pigment epithelium (IPE; n = 672; 18%) or iris stroma (n = 96; 3%). The solid tumors included melanocytic (n = 2510; 68%) and nonmelanocytic (n = 402; 11%). The melanocytic tumors comprised nevus (n = 1503; 60%), melanocytoma (n = 68; 3%), melanoma (n = 645; 26%), and melanocytosis (n = 64; 3%). Of 2510 melanocytic tumors, the first and second most common diagnoses by age (children, young adult, mid adult, senior adult) were nevus (53%, 57%, 63%, and 63%, respectively) and melanoma (17%, 27%, 26%, and 27%, respectively). The nonmelanocytic tumors included categories of choristomatous (n = 4; CONCLUSIONS: In an ocular oncology practice, the spectrum of iris tumors includes cystic (21%) and solid (79%) tumors. The solid tumors were melanocytic (68%) or nonmelanocytic (11%). At all ages, the most common specific diagnoses were nevus (42%), IPE cyst (19%), and melanoma (17%)
